Question 2.
Describe with examples, various types of connective tissues.
Solution:
Connective tissues are most abundant and widely distributed in the body of complex animals. They are named connective tissues because of their special function of linking and supporting other tissues/C ••gans of the body. Connective tissues are classified into three types:
(i) Loose connective tissue,
(ii) Dense connective tissue and
(iii) Specialised connective tissue.
(i) Loose connective tissue:

  • It has cells and fibres loosely arranged in a semi-fluid ground substance, for example, areolar tissue present beneath the skin.
  • Often it serves as a support framework for epithelium. It contains fibroblasts (cells that produce and secrete fibres), macrophages and mast cells.
  • Adipose tissue is another type of loose connective tissue located mainly beneath the skin. The cells of this tissue are specialised to store fats.

(ii) Dense connective tissue :

  • Fibres and fibroblasts are compactly packed in the dense connective tissues.
  • Orientation of fibres show a regular or irregular pattern and are called dense regular and dense irregular tissues.
  • In the dense regular connective tissues, the collagen fibres are present in rows between many parallel bundles of fibres.
  • Tendons, which attach skeletal muscles to bones and ligaments which attach one bone to another are examples of this tissue.
  • Dense irregular connective tissue has fibroblasts and many fibres (mostly collagen) that are oriented differently. This tissue is present in the skin.

(iii) Specialised connective tissue :

  • Cartilage, bones and blood are various types of specialised connective tissues.
  • The intercellular material of cartilage is solid and pliable and resists compression.
  • Cells of this tissue (chondrocytes) are enclosed in small cavities within the matrix secreted by them.
  • Cartilage is present in the tip of nose, outer ear joints, between adjacent bones of the vertebral column, limbs and hands in adults.

Bones : It has a hard and non-pliable ground substance rich in calcium salts and collagen fibres which give bone its strength. It is the main tissue that provides structural frame to the body.
Blood : It is a fluid connective tissue containing plasma, red blood cells (RBC), white bloo4 cells (WBC) and platelets. It is the main circulating fluid that helps in the transport of various substances.

Question 3.
Describe the alimentary canal of earthworm.
Solution:
The alimentary canal is a straight tube and mns between first to last segment of the boay. It has following parts.
Mouth : A terminal mouth opens into the buccal cavity (1-3 segments) which leads into muscular pharynx.
oesophagus: A small narrow tube, oesophagus (5-7 segments), continues into a muscular gizzard (8-9 segments). It helps in grinding the soil particles and decaying leaves, etc.
Stomach : The stomach extends from 9-14 segments. The food of the earthworm is decaying leaves and organic matter mixed with soil. Calciferous glands, present in the stomach, neutralise the humic acid present in humus.
• Intestine starts from the 15th segment onwards and continues till the last segment. A pair of short and conical intestinal caecae project from the intestine on the 26th segment.
Typhosole : The characteristic feature of the intestine between 26-35 segments is the presence of internal median fold of dorsal wall called typhlosole. This increases the effective area of absorption in the intestine.
Anus : The alimentary canal opens to the exterior by a small rounded aperture called anus. The ingested organic rich soil passes through the digestive tract where digestive enzymes breakdown complex food into smaller absorbable units. These simpler molecules are absorbed through intestinal membranes and are utilised.

NCERT Solutions for Class 11 Biology Chapter 12 Mineral Nutrition

NCERT Solutions for Class 11 Biology Chapter 11 Transport in Plants

These Solutions are part of NCERT Solutions for Class 11 Biology. Here we have given NCERT Solutions for Class 11 Biology Chapter 11 Transport in Plants.

Question 1.
“All elements that are present in a plant need not be essential to its survival”. Comment.
Solution:
Plants obtain their inorganic nutrients from the air, water, and soil. Plants absorb a wide variety of mineral elements. Not all the mineral elements that they absorb are required by plants. Out of the more than 105 elements discovered so far, less than 21 are essential and beneficial for normal plant growth and development. The elements required in large quantities are called macronutrients. While those required in fewer quantities or in the trace are termed micronutrients. These elements are either essential constituents of proteins, carbohydrates, fats, nucleic acid, etc. and/or take part in various metabolic processes.

Question 2.
Why is the purification of water and nutrient salts so important in studies involving mineral nutrition using hydroponics?
Solution:
The technique of growing plants in a nutrient solution is known as hydroponics. Since a number of improvised methods have been employed to try and determine the mineral nutrients essential for plants. The essence on all these methods involves the culture of plants in a soil-free, defined mineral solution. These method require purified water and mineral nutrients salts. Purification of water and nutrient salt is important to find out other influencing factors

Question 3.
Explain with examples:
Macronutrients, micronutrients, beneficial nutrients, toxic elements, and essential elements.

Solution:
Based upon the criteria only a few elements have been found to be absolutely essential for plant growth and metabolism. These elements are further divided into two broad categories based on their quantitative requirements,

  1. Macronutrients
  2. Micronutrients

Macronutrients must generally be present in plant tissues in the concentration of 1 to 10 mg/L of dry matter. The macronutrients include carbon, hydrogen, oxygen, nitrogen, phosphorous, sulfur, potassium, calcium, and magnesium. Of these, carbon, hydrogen, and oxygen are mainly obtained from CO2, and H20, while the others are absorbed from the soil as mineral nutrition.

Micronutrients or trace elements are needed in very small amounts (equal to or less than 0.1 mg/L of dry matter). These include iron, manganese, copper, molybdenum, zinc, boron, chlorine, and nickel. In addition to the 17 essential elements named above, there are some beneficial elements such as sodium, silicon, cobalt, and selenium. They are required by higher plants.

Essential elements can also be grouped into four broad categories on the basis of their diverse functions. These categories are:
(1) Essentia] elements as components of biomolecules and hence structural elements of cells, (eg: carbon, hydrogen, oxygen, and nitrogen).

(2) Essential elements that are components of energy-related chemical compounds in plants, for example, magnesium in chlorophyll and phosphorous in ATP.

(3) Essential elements that activate or inhibit enzymes, for example, Mg2+ is an activator for both ribulose bisphosphate carboxylase-oxygenase and phosphoenolpyruvate carboxylase, both of which are critical enzymes in photosynthetic carbon fixation; Zn2+ is an activator of alcohol dehydrogenase and Mo of nitrogenase during nitrogen metabolism.

(4) Some essential elements can alter the osmotic potential of a cell. Potassium plays an important role in the opening and closing of stomata. Any mineral ion concentration in tissues that reduces the dry weight of tissues by about 10 percent is considered toxic. Such critical concentrations vary widely among different micronutrients. The toxicity symptom! are difficult to identify.

Toxicity levels for any element also vary for different plants. Many times excess of an element may inhibit the uptake of another element. For example, the prominent symptoms of manganese toxicity are the appearance of brown spots surrounded by chlorotic veins.

Question 4.
Name at least five different deficiency symptoms in plants. Describe them and correlate them with the concerned mineral deficiency.
Solution:

  1. Chlorosis: Chlorosis is the loss of chlorophyll leading to yellowing in leaves. It is caused by a deficiency of N, K, Mg, S, Fe, Mn, Zn, and Mo.
  2. Necrosis: It is the death of tissue. It occurs due to deficiency of Ca, Mg, Cu, K.
  3. Inhibition of cell division: It occurs due to deficiency of N, K, S, Mo.
  4. Stunted plant growth: It occurs due to deficiency of Ca, N, etc.
  5. Premature fall of leaf and buds: It occurs due to deficiency of calcium, magnesium.

Question 5.
If a plant shows a symptom which could develop due to deficiency of more than one nutrient, how would you find out experimentally, the real deficient mineral element?
Solution:

  1. The deficiency symptoms can be distinguished on the basis pf the region of occurrence, presence or absence of dead spots, and chlorosis of entire leaf or interveinal chlorosis.
  2. The region of the appearance of deficiency symptoms depends on the mobility of nutrients in plants. The nutrient deficiency symptoms of N, P, K, Mg, and Mo appear in lower leaves.
  3. Zinc is moderately mobile in plants and deficiency symptoms, therefore, appear in middle leaves.
  4. The deficiency symptoms of less mobile elements (S, Fe, Mn, and Cu) appear on new leaves.
  5. Ca and B are immobile in plants, deficiency symptoms appear on terminal buds.
  6. Chlorine deficiency is less common in crops.
    NCERT Solutions for Class 11 Biology Chapter 12 Mineral Nutrition 1

Question 6.
Why is it that in certain plants deficiency symptoms appear first in younger parts of the plant while in other they do so in mature organs?
Solution:
The deficiency symptoms tend to appear first in the young tissues whenever the elements are relatively immobile and are not transported out of the mature organs, for example, elements like sulphur and calcium are a part of the structural component of the cell and hence are not easily released.

Question 7.
How are the minerals absorbed by the plants?
Solution:
Uptake of mineral ions, by plants, occurs through
two main phases.
Passive Absorption: It is the process of absorption of minerals through it’s outer space(Intercellular space and cell wall) by physical process. Direct expenditure of metabolic energy is not involved. A substance moves from a region of higher chemical potential to lower chemical potential. It occurs through ion channels (transmembrane protein). The theories to explain the movement of ions:
(a) Ion exchange: Both cation and anion gets absorbed on the surface of cell wall. The absorbed ions are exchanged with ions present in soil solution.
(b) Mass flow hypothesis: According to this hypothesis mass flow of ions occur along with absorption of water as a result of transpirational pull.
Active Absorption: It is the process of movement of ions against a concentration gradient, by utilizing ATP as energy. Both influx and efflux of ions are carried out by carrier mechanism. The activated ions combine with carrier proteins and form ion carrier complex. This complex moves
across all the membrane and reaches inner surface, where it breaks and releases ions into the cytoplasm.

Question 8.
What are the conditions necessary for the fixation of atmospheric nitrogen by Rhizobium? What is their role in nitrogen fixation?
Solution:
Rhizobia are unique because they live in a symbiotic relationship with legumes. Necessary conditions:

  • Requires a strong reducing agent and energy in the form of ATP.
  • The enzyme nitrogenase which is very sensitive to oxygen is required.
  • The processes take place in an anaerobic environment
  • The energy is provided by the respiration of host cells.

The reduction of nitrogen to ammonia by living organisms is called biological nitrogen fixation. The enzyme, nitrogenase which is capable of nitrogen reduction is present exclusively in prokaryotes. Several types of symbiotic biological nitrogen-fixing associations are known. The most common association on roots is nodules. Their role in N2– fixation is to supply the plants with nitrogenase that converts nitrogen to amino acids.

Question 9.
What are the steps involved in the formation of root nodule?
Solution:
Nodule formation involves a sequence of multiple interactions between Rhizobium and the roots of the host plant. Stages in the nodule formation are summarised as follows:
Steps in the development of root nodules:
(a) When a root hair of a leguminous plant comes in contact with Rhizobium, it is deformed due to the secretion from the bacterium.
(b) At the site of curling Rhizobia invades the root tissue and proliferate within root hairs.
(c) Some bacteria enlarge to form membrane-bound structures, bacteroids which cannot divide.
(d) The plants form the infection thread, made up of plasma membrane that grows inward, separating the infected tissue from the rest of the plant.
(e) Cell division is stimulated in the infected tissue and more bacteria invade the newly formed tissues.
(f) It is believed that a combination of cytokinin produced by invading bacteria and auxins produced by plant cells, promotes cell division and extension, leading to nodule formation.

Which of the following statements are true? If false correct them:
(a) Boron deficiency leads to the stout axis.
(b) Every mineral element that is present in a cell is needed by the cell.
(c) Nitrogen as a nutrient element, is highly immobile in plants.

LONG ANSWER QUESTIONS

Question 1.
With the help of a suitable diagram describe the nitrogen cycle.
Solution:
Nitrogen cycle: Plants compete with microbes for the limited nitrogen that is available in the soil. Thus, nitrogen is a limiting nutrient for both natural and agricultural ecosystems.

  • In nature, lightning and ultraviolet radiation provide enough energy to convert nitrogen to nitrogen oxides (NO, NO2, N2O).
  • Industrial combustions, forest fires, automobile exhausts, and power-generating stations are also sources of atmospheric nitrogen oxides.
  • The decomposition of organic nitrogen of dead plants and animals into ammonia is called ammonification. Some of this ammonia

volatilises and re-enters the atmosphere but most of it is converted into nitrate by soil bacteria in the following steps

Name at least five different deficiency symptoms in plants. Describe them and correlate them with concerned mineral deficiency.
Solution:

  • Chlorosis – yellowing of leaves due to loss of chlorophyll caused by the deficiency of N, S, mg, Fe.
  • Necrosis – Death of tissues, especially in leaves caused by the deficiency of Ca, Mg, Ca & K.
  • Delay in flowering caused by the deficiency of molybdenum, nitrogen, and sulphur.
  • Dieback of roots caused by a deficiency of copper.
  • Inhibition of cell division caused by a deficiency of potassium, calcium and nitrogen.

Question 3.
Write notes on :
(a) Reductive animation
(b) Transamination
Solution:
(a) Reduction animation – In this process ammonia (formed by nitrogen assimilation) reacts with a ketoglutaric acid to form the amino acid – glutamic acid. Here ∝ – ketoglutaric acid comes from Kreb’s cycle and hydrogen is donated by co-enzyme NADH or NADPH.
NCERT Solutions for Class 11 Biology Chapter 12 Mineral Nutrition 8

(b) Transamination – Once the glutamic acid is synthesized by reductive amination, other amino acids are synthesized by the transfer of an amino groups to other carbon skeletons. Glutamic acid is the starting material from which 17 other amino acids are formed by the transfer of the amino group of an amino donor compound to the carboxyl position of an amino acceptor compound. Transaminase is the enzyme responsible for such a reaction.

Question 4.
Write an account of the role of mineral elements in a plant.
Solution:
Role of the mineral elements: Plants require mineral elements for various metabolic activities of their body. The following are some of the important functions which the mineral elements perform:

(i) Constituents of the plant body: Elements form the constitution of the plant body. For example carbon, hydrogen and oxygen are essential for the production of carbohydrates hence they are termed framework elements. Nitrogen, sulphur, and phosphorus are required for the synthesis of proteins. Magnesium is an important part of the chlorophyll molecule.

(ii) Influence on the pH of the cell sap: They also influence the pH of the cell sap.

(iii) Maintenance of osmotic pressure in the plant cells: The mineral salts and organic compounds of the cell sap produce necessary osmotic pressure.

(iv) They influence the permeability of cytoplasmic membrane: Different minerals decrease or increase the permeability of plasma membrane.

(v) They have balancing function reactions: Some of the minerals balance the effects of the other.

(vi) They take part in enzymatic reactions: Some elements work as activators while others work as inhibitors in various enzymatic reactions.

NCERT Solutions for Class 11 Biology Chapter 13 Photosynthesis

NCERT Solutions for Class 11 Biology Chapter 13 Photosynthesis

These Solutions are part of NCERT Solutions for Class 11 Biology. Here we have given NCERT Solutions for Class 11 Biology Chapter 13 Photosynthesis.

Question 1.
By looking at a plant externally can you tell whether a plant is C3 or C4 ? Why and how?
Solution:
Plants that are adapted to dry tropical regions have the C4 pathway. They have a special type of leaf anatomy, they tolerate higher temperatures, they show a response to highlight intensities. Study vertical sections of leaves, one of a C3 plant and the other of a C4 plant.

Question 2.
By looking at which internal structure of a plant can you tell whether a plant is C3 or C4? Explain.
Solution:
In C4 plant internal structure of the leaf possess a special type of anatomy called ‘Kranz’ anatomy. ‘Kranz’ means ‘wreath’ and is a reflection of the arrangement of cells.

The bundle sheath cells may form several layers around the vascular bundles; they are characterised by having large number of chloroplasts, thick walls impervious to gaseous exchange and no intercellular spaces.

While in C3 plants, there is no special type of leaf anatomy. There is only a single type of chloroplast inC3 i.e. granal, while in C4 chloroplasts are dimorphic, i.e, granite in the mesophyll cells and agranal in the bundle sheath cells.

Question 3.
Even though very few cells in a C4 plant carry out the biosynthetic-Calvin pathway, yet they are highly productive, can you discuss why?
Solution:
Though these plants have the C4 oxalacetic acid as the first CO2 fixation product they use the C3 pathway or the Calvin cycle as the main biosynthetic pathway.
In C4 plants photorespiration does not occur. This is because they have a mechanism that increases the concentration of CO2 at the enzyme site.
This takes place when the C4 acid from the mesophyll is broken down in the bundle cells to release CO2 this results in increasing the intracellular concentration of CO2 In turn, this ensures that the Rubisco functions as a carboxylase minimizing the oxygenase activity.

Now that you know that the C4 plants lack photorespiration, you probably can understand why productivity and yields are better in these plants. In addition, these plants show tolerance to higher temperatures.

Question 4.
RuBisCO is an enzyme that acts both as carboxylase and oxygenase. Why do you think RuBisCO carries out more carboxylation in C4 plants.
Solution:
RuBisCO or Ribulose bisphosphate carboxylase – oxygenase enzyme can bind to both C02 and O2. This binding is competitive. The relative concentration of C02 and 02 determines which one of the two will bind to the enzyme.

In C4 plants photorespiration does not occur. This is because they have a mechanism that increases the concentration of C02 at the enzyme site.

This takes place when oxaloacetic acid is broken down in the bundle sheath cells to release C02.

It results in increased intracellular concentration of C02. This ensures that the RuBisCO functions as a carboxylase and minimising the oxygenase activity.

Question 5.
Suppose there were plants that had a high concentration of chlorophyll b, but lacked chlorophyll a, would it carry out photosynthesis? Then why do plants have chlorophyll b and other accessory pigments?
Solution:
Though chlorophyll is the major pigment responsible for trapping light, other thylakoid pigments like chlorophyll b, xanthophylls, and carotenoids, which are called accessory pigments, also absorb light and transfer the energy to ‘chlorophyll a’.

Indeed, they not only enable a wider range of wavelengths of incoming light to be utilized for photosynthesis but also protect ‘chlorophyll a’ from photo-oxidation. Reaction centre chlorophyll-protein complexes are capable of directly absorbing light and performing charge separation events without other chlorophyll pigments but the absorption cross-section is small.

Question 6.
Why is the colour of a leaf kept in the dark frequently yellow, or pale green? Which pigment do you think is more stable?
Solution:
Chlorophyll is unable to absorb energy in the absence of light and loses its stability, giving the leaf a yellowish colour. This shows that xanthophyll is more stable.

Question 7.
Look at leaves of the same plant on the shady side and compare it with the leaves on the sunny side. Or, compare the potted plants kept in the sunlight with those in the shade. Which of them has leaves that are darker green? Why?
Solution:
Light is a limiting factor for photosynthesis Leaves get lesser light for photosynthesis when they are in shade. Therefore, the leaves or plants in shade perform lesser photosynthesis as compared to the leaves or plants kept in sunlight. In order to increase the rate of photosynthesis, the leaves present in shade have more chlorophyll pigments.

This increase in chlorophyll content increases the amount of light absorbed by the leaves, which in turn increases the rate of photosynthesis. Therefore, the leaves or plants in shade are greener than the leaves or plants kept in the sun.

Question 8.
The figure shows the effect of light on the rate of photosynthesis. Based on the graph, answer the following questions.
(a) At which point/s (A, B, or C) in the curve is light a limiting factor?
(b) What could be the Jimiting factor/s in region A?
(c) What do C and D represent on the curve?
Solution:
NCERT Solutions for Class 11 Biology Chapter 13 Photosynthesis 1

(a) In the region ‘A’ and half of ‘BTight is limiting factor because rate of photosynthesis is increasing with the intensity of light.
(b) All the other factors except light.
(c) C represents a region where a factor other than light is limiting, e.g., CO2. D represents the light intensity at which rate of photosynthesis is maximum under existing conditions (e.g., CO2).

Question 9.
Give a comparison between the following:
(a) C3 and C4 pathways
(b) Cyclic and non-cyclic photophosphorylation
(c) Anatomy of leaf in C3 and C4.
Solution:
(a) Differences between C3 and C4 pathway

Solution:
9 ATP and 6 NADPH

Question 8.
Why do the stomata of CAM plants open during the night?
Solution:
As these plants grow in dry areas, they keep stomata close during the day to conserve water and open their stomata during the night for the diffusion of gases.

Question 9.
Mention one useful role of photorespiration in plants.
Solution:
It protects the plants from photooxidative damage.

Question 10.
Cyanobacteria and some other photosynthetic bacteria don’t have chloroplasts. How do they conduct photosynthesis?
Solution:
Cyanobacteria have bluish pigment phycocyanin, which they use to capture light for photosynthesis. Some green bacteria (cyanobacteria) are red or pink due to pigment phycoerythrin. Whatever the colour of cyanobacteria, they are photosynthetic and so can manufacture food.

Question 11.
What is phosphorylation? (M.Q.P.)
Solution:
Synthesis of ATP either with the help of light (during photosynthesis) or in presence of oxygen (during respiration) is called phosphorylation.

Question 12.

SHORT ANSWER QUESTIONS

Question 1.
Specify how C4 photosynthetic pathway increases carbon dioxide concentration in bundle sheath cells of sugarcane?
Solution:
In C4 pathway of sugarcane, C02 from atmosphere enters through the stomata in the mesophyll cell and combines with phosphoenol pyruvate to form a 4-C compound oxaloacetic acid. The OAA is then transported to the bundle sheath where it is decarboxylatedto release C02 in bundle sheath.

    (d) Secondary pathway when additional ATP is needed.

Question 5.
What is Blackman’s law of limiting factors?
Solution:
F.F. Blackman (1905) extended a law to formulate the principle of limiting factors. “When a process is conditioned as to its rapidity by a number of separate factors, the rate of the process is limited by the pace of slowest factors.”

Question 6.
In the condition of water stress why the rate of photosynthesis declines?
Solution:
Due to water stress, stomata remain closed and so there is a decrease in CO2concentration and the leaf water potential is also reduced, decline the rate of photosynthesis.

Question 7.
What is a reaction centre? Give the reaction centres of PSI and PSII.
Solution:
Reaction centre is a chlorophyll component of the photosystem and it absorbs as well as accepts energy from other pigments and ejects an electron. The reaction centre of PSII is Chla680 or P680 and PSI is Chla700 or P700

Question 8.
Why is photorespiration considered a wasteful process?

Photorespiration considered a wasteful process because
(i) 25% of photosynthetically fixed carbon is lost in the form of C02.
(ii) There is no energy-rich useful compound produced during this process.

Question 9.
Give two reasons as to why photosynthesis is important for sustaining life on earth.
Solution:
Photosynthesis is the most important process because;
(i) it is the only natural process by which oxygen is liberated into the atmosphere.
(ii) it is the process by which food is manufactured for all living organisms.

Question 10.
Why does the rate of photosynthesis decrease at higher light intensities? What plays a protective role in such situations?
Solution:
Rate of photosynthesis decreases for two reasons :
(i) Other factors required for photosynthesis become limiting.
(ii) Destruction of chlorophyll by photo-oxidation.
Carotenoids play a protective role by:
(i) absorbing the excess light and
(ii) acting as an antioxidant to detoxify the effect of activated oxygen species.

Question 11.

Solution:
The main differences between photosystem I and photosystem II are
NCERT Solutions for Class 11 Biology Chapter 13 Photosynthesis 7

Question 2.
Describe the factors that influence the rate of Photosynthesis. (Oct. 1989)
Solution:
The factors that affect photosynthesis may be both internal & External.

Internal factors:

  • Chlorophyll: it is the light-absorbing pigment and only portions of the plant having chlorophyll can help in photosynthesis.
  • Protoplasmic factor: young seedlings when transferred from darkness to light show the presence of some factors which is believed to be enzymatic initiates photosynthesis and is called the protoplasmic factor.

External factors:

  • Light: It is one of the most important factors which affects the process in 3 ways i.e. quantity, quality, and intensity. Quantity of light is otherwise duration and depends upon the photoperiod that is required by the plant quality refers to the wavelength, maximum photosynthesis occurs in red and blue light while minimum in green light. Intensity favours the process and low intensity decreases the rate of photosynthesis. Very high intensity brings about photooxidation of pigments which is called solarization.
  • CO2: An increase in CO2 concentration favours the process provided other factors are not limiting but very high concentrations are toxic and inhibit photosynthesis.
  • Temperature: Increase in temperature favour photosynthesis but above the optimum range the process decreases due to the denaturation of enzymes.

Question 3.
Explain the process of the biosynthetic phase of photosynthesis occurring in the chloroplasts.
Solution:
The biosynthetic phase of photosynthesis :

  • It occurs in the stroma of chloroplasts.
  • These reactions reduce the carbon dioxide into carbohydrates, making use of the ATP and NADPH2 produced in the photochemical reactions.
  • The reactions are also called as Calvin cycle.
  • The three phases of the Calvin cycle are as follows:

(i) Carboxylation
Six molecules of Ribulose 1,5 bisphosphate
react with six molecules of carbon dioxide to form six molecules of a short-lived 6C- compound.
The reaction is catalysed by RuBP carboxylase (RuBisCo).
The six molecules of the 6C-intermediate break into 12 molecules of 3- phosphoglyceric acid (3-PGA), an SC- compound.
It is through this step that carbon dioxide is fixed in the plant.
NCERT Solutions for Class 11 Biology Chapter 13 Photosynthesis 8
(ii) Reduction
12 molecules of 3-phosphoglyceric acid are converted into 12 molecules of 1, 3 diphosphate-glyceric acid, utilising 12 molecules of ATP and then reduced to 3- phosphoglyceraldehyde making use of 12 molecules of NADPH. Two molecules of phosphoglyceraldehyde react to form one molecule of glucose. It is in this step that there is an actual reduction of carbon dioxide leading to sugar formation.

(iii) Regeneration of RuBP
10 molecules of phosphoglyceraldehyde, by a series of complex enzyme-catalyzed reactions, are converted into six molecules of ribulose 1,5-bisphosphate; six molecules of ATP are needed for this step. This step of ‘ regeneration of RuBP is important for the cycle to continue

Silk Road NCERT Text Book Questions and Answers

Silk Road Understanding the text

I. Give reasons for the following statements.

Question 1.
The article has been titled ‘Silk Road.’
Answer:
The article has been titled Silk Road because it chronicles the author’s expedition to Mount Kailash through the Silk Road region. The name Silk Road or Silk Routes, coined by German geographer and traveller, Ferdinand von Richthofen, refers to a network of trade roads that connected the East and the West. The road’owes its name to the silk trade that was established between China, Europe and Africa.

Question 2.
Tibetan mastiffs were popular in China’s imperial courts.
Answer:
Tibetan mastiff is a ferocious breed of dog found in Tibet. These dogs are used as guards and hunting dogs. These are big dogs with massive jaws. They cock their big heads when they see an approaching stranger and fix them in their sights. They are totally fearless and shoot straight at the stranger like a bullet from a gun. While passing by nomads’ tents, the author’s car was chased by Tibetan mastiffs.

They put up a fierce chase for about a hundred meters and gave up only when they realised the car was off the property. The sinister sight of the dogs and their aggressive behavior made the author realise why the Tibetan mastiff was popular in China’s imperial courts as hunting dogs.

Question 3.
The author’s experience at Hor was in stark contrast to earlier accounts of the place.
Answer:
The earlier travel accounts the author read or heard of presented the town in a completely different light from what he saw before his eyes. He found the place grim and miserable, dusty and rocky with no vegetation. Years of accumulated refuse scattered all over the place. It was an unfortunate sight given the fact that Hor was situated on the shore of Lake Manasarovar.

The author expected something spectacular which would appeal to his senses and his psyche. According to one of the earlier accounts, Ekai Kawaguchi, a Japanese monk who arrived at Lake Manasarovar in 1900, was so moved by the sight that he burst into tears. The same happened to a Swedish traveller, Sven Hedin, who broke into tears too at the Lake. However, the author found his experience in stark contrast to the earlier accounts.

Question 4.
The author was disappointed with Darchen.
Answer:
The author was slightly disappointed in Darchen. To begin with, he had an acute breathing problem. Due to cold as well as the height of the place from the sea level, he felt heaviness in his chest and was unable to breathe every time he tried to lie down. He literally spent the first night in Darchen sitting wide awake against a wall. The problem, however, subsided after he visited a doctor the next day and took Tibetan medicine.

Secondly, the place was dusty and partly neglected. There were heaps of rubbish scattered around. Since the author was too early to arrive, there were hardly any pilgrims in Darchen. He was lonely and felt so because there was hardly anyone who spoke English. Had it not been for a clear sky and a brightly shining sun, Darchen would itself gloomier than ever to the author.

Question 5.
The author thought that his positive thinking strategy worked well after all
Answer:
The author was dejected in Darchen. A bad health, a gloomy town, almost no pilgrims and no one around to talk to made his stay in the town quite demoralising. Although he was trying to boost himself up with positive thinking, his options to make it to Mount Kailash seemed severely limited to him. It was then that he met Norbu, a Tibetan academic, in the only cafe of Darchen. Norbu worked in Beijing, spoke English and was on his way to Mount Kailash.

When the author revealed that that was his intention too, Norbu suggested that they made a team. This was something the author wanted and hoped for. He needed a company, someone who knew the region and could also spoke English. At that point in time, there could not be any better companion for him than Norbu. This made the author feel his positive thinking really worked.

II. Briefly comment on

Question 1.
The purpose of the author’s journey to Mount Kailash.
Answer:
The author, Nick Middleton, is a geographer and a traveller. His purpose of the journey to Mount Kailash was to do the kora, which is the pilgrimage walk around Tibet’s most sacred mountain, Mount Kailash.

Question 2.
The author’s physical condition in Darchen.
Answer:
The author’s physical condition in Darchen was far from being good. He had already been suffering from cold and one of his nostrils was blocked compelling him to breathe through only one nostril. He also suffered from breathlessness due to high altitude. The first night in Darchen was all the more difficult for him as he could not sleep due to heaviness in the chest. This problem, however, was cured by the Tibetan treatment he received the next day.

Question 3.
The author’s meeting with Norbu.
Answer:
The author’s meeting with Norbu was accidental, which, for him was more than a welcome accident. He met Norbu at the cafe of Darchen where he sat pondering over his options of making it to Mount Kailash. Norbu approached the author and struck up a conversation with him. The author was happy to meet Norbu, primarily because he spoke English. Norbu was a Tibetan academic working at the Chinese Academy of Social Sciences, in Beijing. He was in Darchen for the Kailash kora on which he had written many academic papers but never did it himself. When he heard the author also hoped to do the kora, he suggested that they made a team. This was what the author wanted too to complete his expedition and hence it was a happy meeting for him.

Question 4.
Tsetan’s support to the author during the journey.
Answer:
Tsetan was a good guide and a competent driver. He was very careful driving the car in the rough terrain. He knew everything about the region which made the journey of the author quite easy. Tsetan also took care of the author when he fell sick. He took the author to the hospital and saw to it that the latter got proper treatment.

Question 5.
“As a Buddhist, he told me, he knew that it didn’t really matter if I passed away, but he thought it would be bad for business. ”
Answer:
Tsetan was a Buddhist and believed that death was not the end of all. Moreover, passing away at the Manasarovar Lake near Mount Kailash would actually be a good thing. So he told the author that it didn’t really matter if the author passed away at Darchen. However, it wouldn’t be good for his business because if any of his tourists passed away, he would lose his credibility as someone who could not look after his tourists.

Silk Road Talking about the text

Discuss in groups of four

Question 1.
The sensitive behaviour of hill-folk.
Answer:
Hill-folk shown in the text are shown to be very cordial and empathetic towards the narrator. The driver Tsetan shows perseverance to ensure the narrator’s safety, while he struggles with breathing and a persisting cold in the freezing high altitude. The Tibetan doctor’s unusual local medicine help the author with his recovery, while Norbu is willing to team up on their pilgrimage after a brief meeting with the narrator. All these characters show a sense of concern and desire to help visitors adapt to an unfamiliar environment.

Question 2.
The reasons why people willingly undergo the travails of difficult journeys.
Answer:
In this text, the narrator undertakes this difficult journey because he wishes to complete the Kailash kora, a difficult pilgrimage through several rocky mountain passes to the high altitude Mount Kailash. Both Darchen and he are academics, who decide to travel together for scholarly purposes. However, many other pilgrims undertake this difficult journey for spiritual growth. Other reasons that people may undergo such difficult journeys include a desire for such adventures or as tourists a genuine interest in visiting such historic sites.

Question 3.
The accounts of exotic places in legends and the reality.
Answer:
The narrator describes his experiences in the small Tibetan town Hor as very different from the accounts of earlier travellers that he has read. Accounts by a Japanese monk and a Swede visitor describe how they were both sentimentally overwhelmed by the sanctity of the lake. However the narrator describes Hor as a miserable place full of rocks and years of accumulated garbage. This indicates that portrayals in exotic accounts may starkly differ from personal experiences of places.

Silk Road Thinking about language

Question 1.
Notice the kind of English Tsetan uses while talking to the author. How do you think he picked it up?
Answer:
We notice the influence of Tsetan’s mother tongue Tibetan on his use of the English language. Phrases like “Not knowing, Sir” when queried about snowfall and “but no smoking” referring to the car’s petrol tank, indicate that he is relatively comfortable communicating in English and he prefers to use short sentences while speaking the language. As a driver who regularly takes foreign visitors all over Tibet, Tsetan may have learned English through his interactions , with these visitors.

Question 2.
What do the following utterances indicate?
i) “I told her, through Daniel…”
Answer:
This utterance indicate that since the narrator doesn’t speak Tibetan, Daniel translates his sentences from English to Tibetan so he can communicate with Lhamo, to tell her that he plans to complete the kora pilgrimage.

(ii) “It’s a cold, ” he said finally through Tsetan.
Answer:
The doctor, who speaks Tibetan, gets Tsetan to translate his words into English, to inform the narrator that he has a cold and will be giving him medicine to cure this.

Question 3.
Guess the meaning of the following words,
kora , drokba , kyang
In which language are these words found?
Answer:

  • Kora – A Tibetan meditation practice or Pilgrimage
  • Drokba – Tibetan Nomads who manage herds
  • Kyang – Wild asses found in Tibet

Silk Road Working with words

Question 1.
The narrative has many phrases to describe the scenic beauty of the mountainside like:
A flawless half-moon floated in a perfect blue sky.
Scan the text to locate other such picturesque phrases.
Answer:
Other picturesque phrases include:
Extended banks of cloud like long French loaves glowed pink
Sun emerged to splash the distant mountain tops with a rose-tinted blush
Snow-capped mountains gathering on the horizon
River was wide and mostly clogged with ice, brilliant white and glinting in the sunshine.
The trail hugged its bank, twisting with the meanders Big rocks daubed with patches of bright orange lichen.
It was marked by a large cairn of rocks festooned with white silk scarves and ragged prayer flags.
The plateau is pockmarked with salt flats and brackish lakes

Question 2.
Explain the use of the adjectives in the following phrases.

  • shaggy monsters – Tibetan mastiff dogs with lots of fur
  • brackish lakes – Water bodies with lots of salt
  • rickety table – Table that shook because its legs were not fastened well together
  • hairpin bend – A U-shaped bend along a road
  • rudimentary general stores – Basic stores found everywhere that sell most necessary provisions

Silk Road Noticing form

Question 1.
The account has only a few passive voice sentences. Locate them. In what way does the use of active voice contribute to the style of the narrative.
Answer:
What was the likelihood of that I asked.
By late afternoon we had reached.
That night, after my first full day’s course, I slept very soundly.
Once he saw that I was going to live Tsetan left me…
The pilgrimage trail was well-trodden…
The cafe had a single window beside which I’d taken up position…
Active voice is used to indicate that the subject is the person, place or thing that is responsible for the action. The use of the active voice in this narrative puts the reader in the position of the narrator. It makes us identify with his journey as the “I” in the narrative, and also makes us feel like we are travelling along with them through Tibet.

Question 2.
Notice this construction: Tsetan was eager to have them fixed. Write five sentences with a similar structure.
Answer:

  • I was hoping to have the windows repaired.
  • The man was impatiently waiting to have his teeth fixed.
  • The driver was going to have his license cancelled.
  • The kids were waiting to get their ice-cream cones refilled.
  • The teacher was longing to have her tenure extended.

Note Making Class 11 CBSE Format, Examples

I. How to make notes:

1. Read the passage carefully.

2. Give a heading to your work. The heading will be based on the following considerations.
(i) What is the main idea of the passage?
(ii) Frame a heading based on the main idea.
(iii) Write it in the middle of the page.

3. Give subheadings
(i) How has the main idea been presented and developed?
(ii) Are there two or three subordinate/associated ideas?
(iii) Frame subheadings based on these.

4. Points are to be noted under each subheading.

Are there further details or points of the subtitles that you wish to keep in these notes? These are called points. Points may have subpoints.

5. All subheadings should be at a uniform distance from the margin.
6. Indenting – Points should also be at the same distance away from the margin.
7. Do not write complete sentences.
8. Abbreviations should be used.

II. Help with abbreviations:

1. Use standard abbreviations and symbols as far as possible.

(i) Capitalise the first letters of the names of states, countries or organisations.
For example: UP, USA, UK and UNO.

(ii) Common abbreviations
Sc. (for science), Mr, Mrs, Dr, govt, BSc, etc.

(iii) Common symbols such as i.e., e.g., Rx, /, ∴ , +ve, -ve, → (leading to) ↑ (rising), ↓ (falling), =, >, <

(iv) Measurements and figures – 100″, 100′, 100 kg, 100 mm, 100 mL.

2. Make your own abbreviations.

(i) Keep the main sounds of the words: edn (education), progm. (programme).
(ii) It is a good practice to keep the first few and the last letters of the word such as education – edu’n, developing – dev’ing. Retain the suffix so that later when you are going over the notes, you may recall the full form of the word, for example: ed’nal (educational), prog’ve (progressive).

3. Take the following caution:

(i) Do not get overenthusiastic about abbreviations.
(ii) You should not abbreviate every word.
(iii) One abbreviation in one point is enough.
(iv) As a general rule, the heading should not be abbreviated.
(v) You may use abbreviations in subheadings.

III. Your notes should look like this:

(i) Indenting is essential.

Note Making Class 11 1
Notice that indenting, i.e. shifting from the margin, has been used to clearly indicate subheadings, points and subpoints. Subheadings, though separated by points, occur below one another. Similarly, points and subpoints should also come below one another. Such use of indenting gives your notes a visual character. At a glance, you can see the main idea and its various aspects.

(ii) Numbering-You may follow any system but you should be consistent, that is, you should follow the same system throughout. Some examples are given below.
Note Making Class 11 2

IV. Abbreviations:

Note-making is an informal exercise as it is meant for your use only. You will not present a formal document in note form. Notes will be developed into a more formal piece of writing. Since notes are informal and are meant for your use only, you can abbreviate long words or use accepted abbreviations and symbols.

Writing a summary: The summary is an abstract of the passage. Expand your heading and subheadings and write down the ideas developed in the passage in the specified word limit.

1. Read the passage given below and answer the questions that follow: [NCT 2018]

1. Flexibility and mobility are essential not only to reduce the risk of injuries but to generally feel better. Living a nine to five desk life can be demanding on health and wellness. Here is how you can keep the most common problems at bay.

2. Even if you are not exercising you need to make sure that you maintain correct posture and sit at your desk in the right way. It is important that your chair is placed correctly and your legs are not left hanging. Proper alignment ensures that your neck and back are not strained. Exercises and abdominal crunches two to three times a week can strengthen the core. It will help take the pressure off your back and will make it easier to maintain good posture. Chairs with a back that support your upper back are preferable for those who work long hours in front of screens.

3. Constant typing, writing reports, and answering e-mails can exert your wrists leading to long-term damage. The frequency of your use and how you position your wrists at your keyboard can be a reason. The telltale signs of exertion would be a tingling sensation or numbness. One should not ignore initial signs. Make sure that you rest your wrist at regular intervals. To relieve tension quickly fold your hands in a NAMASTE in front of your chest with elbows moving out and lower your hands till you feel a good stretch in your wrists. Also rotating your fists inside and outside provides much relief to strained wrists.

4. Since those who work on desks spend a lot of time looking at a computer screen, they are at a risk of straining their eyes. This may also lead to dry eyes and fatigue. Poor eyesight is the result of continued and improper exposure to screens. Keeping the computer screen at an optimal distance helps a lot in minimising strain to eyes. The screen shouldn’t be too close or too far. To ease eye strain use good lighting and make it a point to look at a distance away from your screen every twenty to thirty minutes.

(a) On the basis of your reading of the above passage make notes on it using headings and subheadings.
Use recognisable abbreviations and a format you consider suitable. Also, supply a title to it.
(b) Write a summary of the passage in not more than 80 words using the notes made.

(b) Summary

Desk users are at risk of losing flexibility, mobility, and wellness due to long working hours. Good selection of office chairs and proper posture are essential for neck and back health. Damage to the wrists can be prevented by exercising them frequently. Eyes too are at a risk due to looking at the computer screen for long. Optimal distance from the screen will prevent fatigue, dry eyes and poor vision. Good lighting is essential. One should look away from the screen every 20-30 minutes.

2. Read the passage given below and answer the questions that follow: [NCT 2017]

1. Jahangir was born on 30 August 1569, to Akbar, the Mughal Emperor, and his Hindu wife, Jodha Bai. He was crowned on 24 October 1605. In the twenty-two years, he was Emperor, till his death on 28 October 1627, he had many battles to fight and many rebellions to suppress. But he always found time for his greatest hobby-the study of animals and plants. He was an avid bird watcher or an ornithologist as he would be called now, and a keen naturalist. The care and accuracy with which Jahangir described various characteristics of animals and birds, their geographical distribution and behaviour, would have done credit to a full-time naturalist. His observations are recorded in his memoirs, the Tuzuk-i-Jahangiri.

2. Jahangir had a small zoo and he would spend hours-sometimes days and nights together-on his observations. For the first time in the history- of ornithology, he noted how sarus cranes mate brood over their eggs in turn, and how chicks are hatched and taken care of. He also observed one human quality in this bird: the parents love not only their eggs and chicks but also each other.

3. The Emperor had several famous painters in his court. When he came across a rare animal, bird or plant, he would instruct an artist to draw it. The painter who excelled in this art was Ustad Mansur. For modern ornithologists, Jahangir’s collection of paintings provides a strikingly accurate description of the natural history of the day. Unfortunately, most of these paintings are no longer to be found in India. With the disintegration of the Mughal Empire, foreign adventures looted this treasure. Most of the paintings were thus lost.

4. In 1958, a Russian researcher, A Ivanoc, created a sensation when he discovered, a rare portrait of the dodo, a large non-flying pigeon-like bird, which became extinct about three centuries ago. This portrait was found in a collection of paintings at the Institute of Orientalists of Soviet Academy of Sciences. There was no way of identifying the painter, but the style, without doubt was that of Ustad Mansur. Now there is evidence to show that it was the portrait of Mauritian dodo that was presented to Emperor Jahangir around 1624. Over three centuries after their death, Jahangir and his dodo made a dramatic reappearance in the world of ornithology!

5. Jahangir also loved gardens, but his dissertations in botany and horticulture were mostly confined to how a lotus traps hornets or how saffron sprouts from soil. However, he was responsible for the cultivation of high altitude trees such as the cypress, juniper, pine and Javanse sandal in plains.

6. Jahangir had many other scientific interests. He once conducted an experiment to show that the air of Mahmudabad (in Gujrat) was healthier than that of Ahmedabad. He was fascinated by the movement of the stars and the planets and used to regularly record the occurrence of solar and lunar eclipses. When a comet made its appearance, he recorded the growth and decay of its tail.

(b) Summary

Emperor Jahangir was a keen naturalist. He loved to observe birds and animals and had the rare ones painted by skilled artists like Ustad Mansur. A portrait of an extinct Maurition Dodo was discovered by A. Ivanoc, a Russian researcher.

Jahangir had a small zoo, where he observed birds and animals, particularly sarus crane. He noted his observations on the behaviour and geographical distribution in his autobiography Tuzuk-i-Jahangiri.

Besides, he had an interest in horticulture, stars and planets, eclipses, and even in the purity of air in various cities.

3. Read the passage given below and answer the questions that follow: [NCT 2016]

Effective speaking depends on effective listening. It takes energy to concentrate on hearing and to concentrate on understanding what has been heard. Incompetent listeners fail in a number of ways. First, they may drift. Their attention drifts from what the speaker is saying. Second, they may counter. They find counter-arguments to whatever a speaker may be saying. Third, they compete. Then, they filter. They exclude from their understanding those parts of the message which do not readily fit with their own frame of reference. Finally, they react. They let personal feelings about the speaker or subject overside the significance of the message which is being sent.

What can a listener do to be more effective. The first key to effective listening is the art of concentration. If a listener positively wishes to concentrate on receiving a message, his chances of success are high!

It may need determination. Some speakers are difficult to follow either because of voice problems or because of the form in which they send a message. There is then a particular need for the determination of a listener to concentrate on what is being said.

Concentration is helped by alertness. Mental alertness is helped by physical alertness. It is not simply physical fitness but also positioning of the body, the limbs, and the head. Some people also find it helpful to their concentration if they hold the head slightly to one side. One useful way for achieving this is intensive notetaking, by trying to capture the critical headings and subheadings the speaker is referring to.

Note-taking has been recommended as an aid to the listener. It also helps the speaker. It gives him confidence when he sees that listeners are sufficiently interested to take notes, the patterns of eye contact when the note taker looks up can be very positive; and the speaker’s timing is aided he can see when a note-taker is writing hard and can then make effective use of pauses.

Posture too is important. Consider the impact made by a less competent listener who pushes his chair backward and slouches. An upright posture helps a listener’s concentration. At the same time, it is seen by the speaker to be a positive feature amongst his listeners. Effective listening skills . have an impact on both the listener and the speaker.

(a) On the basis of your reading of the above passage make notes on it using headings and subheadings. Use recognizable abbreviations wherever necessary and also suggest a suitable title.
(b) Write a summary of the passage in not more than 80 words using the notes.

Answer:
(a) Effective Listening Leads to Effective Speaking

1. Incompetent listening

(a) attention drifts
(b) lis’nr counters arguments and competes
(i) filters msgs
(ii) reacts to the msg

2. How to listen effectively

(a) concentration is needed
(i) alertness helps in concentration
(ii) physical fitness → mental alertness

(b) Note-tkg aids effective listening
(i) lis’nr tries to capture the main pts
(ii) note-tkg helps the spkr too

(c) Determination is needed to
(i) overcome voice and other pecul iarities
(ii) decipher the form of the msg

(d) Posture helps
(i) upright posture of lis’nr helps in concentration
(ii) helps the spkr

3. Conclusion

Effective listening impacts the lis’nr and the spkr

Key to abbreviations:

lis’nr – listener
msg – message
tkg – taking
pts – points
spkr – speaker

(b) Summary:

Good listening can aid the speaker and can lead to good speaking. Incompetent listeners disturb good speaking by countering the speaker or by competing with him.

For good listening concentration on receiving the message is needed. Determination to receive the message, mental alertness, and good posture help. Taking notes is also an aid to concentration and good listening.

Good listening helps the speaker through eye contact. An attentive posture of the listener increases the speaker’s confidence.

4. Read the passage carefully and answer the questions that follow: [NCT 2015]

1. Twenty-one-year-old Jyoti Amge, the smallest woman in the world, laughs easily and often. Perhaps, from a height of twenty-three inches, the world does look a bit funny.

Afflicted with achondroplasia, a form of pituitary dwarfism, 21-year-old Amge is a bit shorter than her two-year-old nephew and a lad taller than her framed Guinness certificate. In fact, Amge, the youngest of five, wasn’t even visible in her mother’s womb. The doctors thought she wasn’t alive and her mother Ranjana, who underwent a two-hour caesarian operation in her tenth month to birth her, welcomed her youngest as a blessing. In all of Amge’s birthday pictures in the album, her height is the same from age three to twenty-one. Kitted out in custom made frocks and bright red lipstick; with fancy beads lining her permed hair, the tiny Amge turned heads in Nagpur and became a hit with Hindi news channel crews that approached her for bytes, any excuse would do, even the elections. Apart from a cameo in a Mika Singh video, she appeared briefly on the reality show Big Boss 6.

“I have always wanted to be an actor,” says Amge. Amge was quick to say yes when the producers of ‘American Horror Story’ Freak Show contacted her. “They had seen my interview in a New York daily,” says Amge, who readily agreed to play the role of Ma Petite, the miniature sari- and-bindi-clad assistant of a woman.

“In spite of the name the show was not about freaks it was about compassion,” says Amge. “What makes the world so interesting in that we are different and some folks a little bit odd,” she said. Sadly, Amge’s own home country does not seem to respect differences. Amge’s brother complained that unlike the West where “people ask permission before clicking a photo,” Indians take her privacy for granted. People look at her like she’s a wonder, an ajooba and try to get too close to her. I have to shelter her like a body guard, adds Satish.

Amge’s family members now make up her entourage. They help Amge, who suffered an accident in Kashmir that severely fractured her left leg, with everything from braiding her hair to carrying her to the washbasin. Be it the nearby mall or a trip to China, one or more of them always accompany her.

(a) On the basis of your reading make notes on the above passage. Using abbreviations where necessary. Give a suitable title to your notes.
(b) Write the summary of the passage in your words. Don’t forget to write the title.

Answer:
(a) 1. Jyoti Amge: The smallest woman in the world.
(i) only 23″ tall at 21 years of age
(ii) dwarf due to achondroplasia
(iii) was not visible in her mother’s womb
(iv) same ht from 3 to 21 years.

2. Media exposure
(i) Jyoti a hit on a Hindi news chnl in Nagpur
(ii) cameo in a Mika Singh video and Big Boss 6
(iii) ‘American Horror Story’ a Freak Show of the US

3. No respect for privacy in Ind
(i) Ppl stare at her
(ii) Fml has to shelter her or accompany her.

Key to abbreviations:

ht – height
chnl – channel
Ind – India
ppl – people
fml – family

(b) Jyoti Amge: The Smallest Woman in the World

Jyoti Amge is twenty-one years old and only 23” tall. She is the world’s smallest woman. She did not gain height after three years of age due to achondroplasia. Jyoti caught the attention of a Hindi news channel in Nagpur. She featured briefly on a Mika Singh’s video and the reality show Big Boss 6. She played a role in the American Freak Show named American Horror
Story.

In India, however, Jyoti’s privacy is not respected. Her family remains close to her in order
to protect her.

5. Read the passage given below and answer the questions that follow: [NCT 2014]

1. Everyone needs a holiday, both to relax and to have a change of environment. The holidaymakers feel relaxed and refreshed at the end of the holiday and look forward to the resumption of their duties, be it at school, office, or factories, with renewed vigour. This is the reason why all establishments grant their employees annual leave. With the end of the academic year, the schools and universities grant their pupils a long holiday during mid-summer. This lasts until early September when the new school term starts. Of course, the parents will like to take advantage of this and take their leave to coincide with the children’s vacations. This has become a traditional holiday season in most European countries, particularly in England.

With the coming of August, the traditional holiday season in Britain reaches its peak point and most of the holiday resorts are packed to capacity. In order to avoid the crowd, some prefer to take their holiday a little earlier if facilities so warrant. Those who have already taken their holidays can console themselves not only with reflections on the happy days spent in the country, at the seaside or abroad but also with the thought that holiday expenses are over for the year and that by taking an earlier holiday they have missed the August rush.

The main thing, of course, is the weather and that would be hazardous to prophesy. But whatever the weather is like, the essence of a holiday for most is the carefree atmosphere in which it can be enjoyed. “Take all you need but leave your worries behind” is the sound advice for the holidaymaker. Private worries are not always easy to escape from. However, even the pessimist would admit that for the moment things appear brighter than they have been.

Holiday time is surely a time for shedding serious pre-occupations and seeking the pleasures that appeal to us. It is true that we may not always succeed in finding them, indeed there are people who maintain that the great thing about the holiday is that it gives you an ampler appreciation of home comforts – a view no doubt more widely held among the elderly than you.

(a) On the basis of your reading the above passage, make notes using headings and subheadings. Use recognizable abbreviations, wherever necessary. And also suggest a suitable title for it.
(b) Write a summary of the above passage in not more than 80 words using the notes made by you.
Answer:
(a) Importance of Holidays

1. Need for holidays
(i) holidays give relaxation to students and workers
(ii) establishments grant annual holidays
(iii) schools and univs give holidays mid-summer
(iv) Aug-Sept are holidays season in Europe, England

2. Aug-Sept peak holiday season
(i) resorts packed to capacity
(ii) some take early holidays in Aug.

3. Carefree atmosphere-the essence of holidays
(i) weather may be bad
(ii) private wor’s are difficult to forget
(iii) we shed wor’s during holidays
(iv) Holidays give us keener appr’cn of home comfort

Key to abbreviations:

Univs – universities
Aug – August
Sept – September
Wor’s – worries
Appr’cn – appreciation

(b) Holidays are important in our lives because they provide us with relaxation. All establishments and academic institutions grant holidays in summer. August and September are holiday seasons in Europe and England.

In August most holiday resorts in Britain are packed to capacity. Some people take their holidays a little early in order to avoid the crowds.

The most important thing is to have a carefree atmosphere even though private worries are difficult to get rid of. During holidays we acquire ampler appreciation of home comfort.

6. Read the passage given below and answer the questions that follow:

1. When planning to go on a vacation, the tendency is to make sure that the travel plans are hassle free, before stepping out of one’s doors. This involves booking by train, bus or even by air to one’s chosen destination. Yet the greatest holidays can be enjoyed by going on foot and I am not referring to trekking expeditions into the wilds. Any holiday can be made into a walking trip by opting out of a bus ride or a train journey or a taxi drop, by selecting to go on foot. Besides, walking is a great form of exercise and, above all, helps you to go deep into the local culture, the daily lives of people, their food and their music.

2. Walking helps you enhance the adventurous streak in you. If you are out on a beach holiday, instead of workouts at the gym, head out to the water for your exercise. Resort pools are a great way to have fun and stay fit and are suitable for all ages. Wake up early to start your day with a swim and you can also recruit family and friends to join in to make the activity even more interesting.

3. The best holiday destinations need not be those that the travel brochures advertise. It can be one of your own search, if you take advantage of what an area is known for and then set out to explore it on your own terms. Thus you can learn tai chi when on a trip to China or smarten up your dancing skills by trying out flamenco when in Spain.

4. In order to enjoy a walking holiday to the hilt, one needs to be physically in form. Thus one needs to keep a tab on one’s diet when on holiday. The travel brochures give you a choice of tried-out brands with a peppering of local options. But whatever be your choice, it is smart to stick to the rule book. In every place you are sure to find fresh and healthy high-protein, high- fibre options to fill you up. That will keep you away from opting for the high sugar, processed foods, and simple carbohydrates.

5. These simple rules would ensure that your walking holiday was not only enjoyable but one that left you feeling fully in command of your holiday mood and proved economical as you did not waste a single moment nursing an upset belly or a sluggish day or a boring ride across acres of , non-stimulating countryside, cooped in a taxi or jostling on a train.

(a) On the basis of your reading of the above passage, make notes on it, using headings and
subheadings. Use recognisable abbreviations (wherever necessary-minimum four) and a format you consider suitable. Also supply an appropriate title to it.
(b) Write a summary of the passage in about 80 words.

Answer:
(A) ‘Walking Holidays’
Notes:
1. Planning a vacation involves

1. making it hassle-free
2. bookings in advance
3. options of air, train, bus, taxi

2. Choice of a walking holiday

1. great form of exercise
2. allows going deep into local culture
3. selections of cuisine and music
4. explore area beyond travel brochure info.

3. Comb walking holiday with holiday choices

2. Resort holiday: early morning swim

4. Food intake on a walking holiday

1. necessity of keeping fit by choosing what to eat
2. high fibre, high prot options preferred
3. curbs opting for high sugar, simple carbs and processed food

5. Advs of food selections

1. feel fully in comd of your holiday
2. no time wasted over upset belly, or sluggish day
3. keeps off boring taxi rides across the non-stimulating countryside

Abbreviations used

info – information
carbs – carbohydrates
comd – command
combo – combining
prot – proteins
Advs – Advantages

(b) Summary

Conventional holiday planning involves making bookings by air, train or taxi. Yet the choice of a walking holiday allows opportunities of delving into local culture, exploring areas not included in travel brochures. Workouts on a beach for beach holidaymakers and use of a resort pool at resort destinations are the usual modes of exercise on a holiday. Walkers, though, need to keep an eye on dietary intakes, settling for high fibre, high protein options to ward off high sugar, simple carbohydrates, and processed foods. This regimen keeps walkers fully in command, minus upset Stomachs and boring taxi rides.

7. Read the passage given below and answer the questions that follow:

1. We are all now aware that some new scientific or technological advance, although useful, may have unpleasant side effects. More and more the tendency is to exert caution before committing the world to something that may not be reversible.

2. The trouble is, it’s not always easy to tell what the side effects will be. In 1846, Ascanio Sobrero produced the first nitroglycerine. Heated, a drop of it exploded shatteringly. The Italian chemist realised in horror its possible application to warfare and stopped his research at once. It didn’t help, of course. Others followed it up and other high explosives were indeed being used in warfare by the close of the nineteenth century.

3. Did that make high explosives entirely bad? In 1867, Alfred Nobel learned how to mix nitroglycerine with diatomaceous earth to produce a safer-to-handle mixture he called ‘dynamite’. With dynamite, earth could be moved at a rate far beyond that of pick and shovel and without brutalising men by hard labour. It was dynamite that helped forge the way for railways, that helped build dams, subways, foundations, bridges, and a thousand other grand-scale constructions of the industrial age.

4. A double-edged sword of good and evil has hung over human technology from the beginning. The invention of knives and spears increased man’s food supply-and improved the art of murder. The discovery of nuclear energy now places all the earth under the threat of destruction-yet it also offers the possibility of fusion power as an ultimate solution to men’s energy problems.

5. Or think back to the first successful vaccination in 1876 and the germ theory of disease in the 1860s. Do we view medical advance as dangerous to humanity, or refuse to take advantage of vaccines and antitoxins, of anesthesia and asepsis, of chemical specifics and antibiotics? And yet the side effects of the last century’s medical discoveries have done more to assure civilisation’s destruction than anything nuclear physicists have done. For, the population explosion today is caused not by any rise in average birth rate but by the sharp drop-thanks to medicine-in the death rate.

6. Does that mean science should have avoided improving man’s lot through medicine and kept mankind a short-lived race? Or does it mean we should use science to correct the possibly harmful side effects, devise methods that would make it simpler to reduce the birth rate and keep it matching the falling death rate? The latter, obviously.

7. About 8000 B.C., mankind invented agriculture. Again it made possible an increase in numbers. People had never eaten so well, but it meant they had to give up the free, nomadic life and remain bound to the soil. It meant hard labour. It meant banding together to fight off surrounding tribes who, still food gathering, might help themselves to your crops. It also meant the risk of crop failures.

8. Where irrigation was introduced to make harvest more dependable, it meant the formation of a large political unit, the social tyranny of a king, an aristocracy, a priesthood. And, even if the land grew prosperous and populous, any infectious disease that got started ran through the crowded population like wildfire. ’

9. Why not, then, go back to the wilder, freer ways of hunting and food gathering? Wouldn’t that mean less work and worry, less war, less pestilence?

10. But you can’t! Abandon agriculture and, out of every 10,000 people, only 100 survive. No, the problems to which agriculture gave rise could be solved only by moving forward with additional advances in technology-the use of oxen in place of men, horses in place of oxen, crop rotation, fertilisers, etc.

11. We’can save, conserve, cut out waste, but what we have, we must keep. The only solution, as always in the history of mankind, is to solve problems by still further advances in technology.

(a) Make notes on the passage in any suitable format using recognisable abbreviations, wherever necessary. Give a suitable title to your notes.

3.2. Solve problems by still further advancement in technology.

Key to abbreviations:

mov’g – moving
railws – railways
sol’n – solution
inc – increase
destr’ve – destructive

(b) Summary

Scientific advancements, however beneficial, have some harmful side effects. We need to be cautious before introducing an advancement, the side effects of which may be irreversible. High explosives have immense destructive power but can be used for earthmoving and construction. Best of all, they free men of manual labour. Similarly, knives and spears and even nuclear energy have good as well as bad uses. Vaccinations controlled disease, but also caused the population explosion, similarly, agriculture and irrigation brought settled societies but also the tyranny of kings.

Whatever happens, we cannot give up scientific advancement. Rather, if science creates problems, we have to solve them with more scientific advancement.

8. Read the passage given below and answer the questions that follow:

1. It must have been a terrible experience. The earthquake began with strong side-to-side movements which knocked down any person who was standing. Then there were up-and-down movements, a vast rumbling and reverberating noise as of an artillery bombardment or a hundred aeroplanes in the sky, and whter gushed out in innumerable places out of huge fissures and craters and rose to about ten or twelve feet. All this probably lasted for three minutes or a little more, and then it died down; but those three minutes were terrible enough. It is not surprising that many persons who saw this happen imagined that this was the end of the world. In the cities, there was a noise of falling houses, and rushing of waters, and an atmosphere full of dust which made it impossible to see even a few yards. In the rural areas, there was not much dust and one could see a little farther, but there were no calm-eyed spectators. Those who survived lay flat on the ground or rolled about in an agony of terror.

2. The city of Monghyr was the last place in our tour. When we saw Monghyr and the absolute destruction of this rich city, we gasped and shivered at the horror of it.

3. All over the earthquake areas there was a very painful absence of self-help among the residents, both in the cities and villages. Probably, the middle classes in the cities were the worst offenders in this respect. They all waited for somebody to take action and help them, either the Government or the non-official relief agencies. Others who offered their services thought that the work meant ordering people about. Part of this feeling of helplessness was no doubt due to the nervous collapse brought about by the terror of the earthquake, and it must have gradually lessened.

4. In marked contrast with this was the energy and capacity of the large numbers of relief workers – who poured in from other parts of Bihar and other provinces. It was wonderful to see the spirit of efficient service of these young men and women and, in spite of the fact that a host of separate relief organisations were working, there was a great deal of co-operation between them.

5. Of all the non-official relief organisations, the Central Relief Committee, of which Rajendra Prasad was the head, was by far the most important. This was by no means a purely Congress organisation, and it developed into an all-India body representing various groups and the donors. It had, however, the great advantage of having the Congress organisation in the rural areas at its disposal.

6. The Relief Committee availed itself of this fine organisation to reach the peasantry. In the rural areas, no other agency, not even the Government, could be so helpful. And the head of both the Relief Committee and the Bihar Congress Organisation was Rajendra Babu, the unquestioned leader of Bihar. Looking like a peasant, a typical son of the soil of Bihar, he is not impressive at first sight, till one notices his keen frank eyes and his earnest look. One does not forget that look or those eyes, for through them truth looks at you and there is no doubting them. His outstanding ability, his perfect straightness, his energy, and his devotion to the cause of Indian freedom are qualities which have made him loved not only in his own province but throughout India.

In contrast, the young relief workers from Bihar and other places were full of energy and spirit of service. There was cooperation among various teams.

Of all the teams, Dr. Rajendra Prasad’s team was the most important. It had the support of the Congress Party in rural areas too. Rajendra Babu was the unquestioned leader of Bihar.

9. Read the passage given below and answer the questions that follow:

1. Leadership is very unique chemistry which happens when the best of everything gets together to create magic.

2. The New Testament says: “As Jesus passed on from there, he saw a man named Mathew sitting at the tax office and said to him, ‘Follow me.’ So he rose and followed him.” No questions, no arguments, no hesitation. What is that mysterious, intangible, electric elusive quality known as leadership?

3. The inevitable million-dollar question that keeps cropping up is “Are leaders born with a natural capability to lead or do they learn to do so?” And the surprising answer is-both. Organisational capabilities and individual brilliance are something they are born with. But fine points such as patience, humility, and appreciating opinion different from one’s own, are all acquired in time. As G.B. Shaw once remarked, “The golden rule is that there are no golden rules.” One can never pinpoint with absolute accuracy all the traits that a leader requires. They change from time to time and situation to situation.

4. The true qualities of a person emerge in the face of adversity. So is it with leaders? Look at any person who has the rare ability to lead, the first thing you find is how cool and self-composed he is even in times of crisis. In the midst of chaos, he sets out in right earnest setting things right, restoring normalcy, and soon things are back to normal.

5. A leader has to be a visionary; he must be able to draw inspiration from the past and envision a future brighter than the present, however difficult that might seem. He has to be very clear about the vision-what he is serving and the mission-what he must achieve.

6. Another distinguishing trait of leaders is their organisational ability, the ability to coordinate together individual efforts into a single one.

7. A leader has the capability of bringing out the best in the people he leads and cultivate a team spirit. He allows others to solve the problem rather than taking it on single-handedly. He has to communicate very well so as to gain the confidence of others so that they feel they are on the right track and then they would be ready to lay down their lives.

8. He has to be patient, to listen to others’ grievances, and hence half the battle is won.

9. A leader has to be a highly efficient manager as well as a coordinator. He might have to set an example before the rest. His individual work has to be flawless.

10. “A leader is a dealer in hope,” said Napoleon.

11. The success of leaders is finally measured not only in terms of how capable they appear, or how well they are able to perform as individuals but how successful they are in leading their team to perform.

12. A leader has the capacity and will to rally men and women to a common purpose.

10. Read the passage given below and answer the questions that follow:

1. The nine-letter word “interview” can cause the most knowledgeable and strong people in the world to perspire. That may be one reason, political leaders and corporate giants normally do not agree for an interview. But the popular ones, or those who want to make an impact, willingly give interviews. In modern times, whether you like interview or not, your prospects depend on its success. So you must know what an interviewer expects from you.

2. First an academic question. What is an interview? It is a discussion in which an interviewer faces a candidate for a short while and asks questions to probe his knowledge and awareness on the subject. This is done to assess the personality of the interviewee. It is a very formal means of interaction with one person facing a group of persons, each of whom is a specialist in his or her field.

3. Knowledge is an important component of success in an interview. It has two aspects: range and depth. The former implies that you should know a lot beyond your own specialisation and the latter means an awareness of the various aspects of the topics under discussion. In-depth knowledge is gained through reading and listening. Listening is more important than reading. Be a keen listener, store major facts in your mind, and use them at the appropriate time.

4. Next comes appearance, which means your dress for the interview. You must be elegantly attired for the occasion. Wear a simple outfit that suits your physique and features. Women should wear sarees or any other sober dress. Casuals like kurta-pajama should not feature in your selection of dresses.

5. Conducting yourself in an apt way is equally significant. The way you move, sit on the chair, place your hands, and your briefcase, and talk to the members reflect your behaviour. Walking sloppily, talking loudly or inaudibly, getting irritated easily, and showing documents insistently are symptoms of bad behaviour. A better way is to enter the room smartly, move forward with dignity, greet the board, sit when asked to, and thank at the end before you leave.

6. Expression is the most important aspect of the interview. It conveys your views and opinions. For good expression, what you need is clarity of mind and speech. Show your balanced thinking to convey your views clearly.

7. Convey your views effectively. In an interview, you may be asked questions where you have to either agree or disagree. Whatever your approach, convince the board that it is unbiased. The board may not agree with your view. Even if you disagree, let not your face show it. Create an impact through your expressions. Give the impression of being a leader. Show that you can cooperate and get the cooperation that you can share views and get people to accept your authority to reach decisions, and implement them.

8. Finally, never consider yourself to be a perfect man. Being a human being makes you susceptible to flaws. However, try to conform to the highest standards and reach as close to perfection as possible.

11. Read the passage given below and answer the questions that follow:

1. Everyone knows that smoking and chewing tobacco is bad for health, yet 250 million people in India-almost one-fourth of the country’s population-consume some form of tobacco. “People think that they can give up tobacco use whenever they want, but it’s not that easy. Nicotine is an addictive drug,” former health minister Dr Ambumani Ramadoss told the Hindustan Times.

2. The World Health Organisation links smoking to 25 cancers-head and neck, urinary bladder, kidneys, cervix, pancreas and colon, to name just a few. Smoking is also a major risk factor for several other diseases such as chronic bronchitis, heart disease, stroke, impotence and premature death.

3. “Most people link smoking to cancers, but it is the biggest cause of heart disease. Smoking increases the risk of clot formation in the blood, which can block arteries and cause heart attack even in healthy people,” says Dr R.R. Kashiwal, Director, Cardiology, Escorts Heart Institute and Research Centre. “Lifestyle changes don’t help much if a person continues smoking,” he adds.

4. Smoking causes about 30 percent of all cancer deaths (including 90 percent of lung cancer deaths). According to the Indian Council of Medical Research, one million people die from tobacco use in India every year. Reducing tobacco use is naturally a big priority for the health minister.

5. Despite the cigarettes and other tobacco products (packaging and labelling) rules banning smoking in public places and sale to minors in India, the number of smokers is going up each year. “About ten million children under the age of 15 are addicted to tobacco in India,” says Ramadoss.

6. The WHO estimates that of every 1,000 tobacco users today, 500 will die of a tobacco-related disease, 250 of them in their middle age. The current tobacco consumption trend in India indicates a shoot up from 1.4 percent of deaths in 1990 to 13.3 per cent in 2020.

7. A proposal to carry graphic and direct health warnings such as “Tobacco Kills”-on all tobacco packages has been postponed indefinitely because of pressure from the food industry, which claims farmers and poor workers will lose jobs. But thousands of lives will be saved if the new warnings drive home the health hazards of tobacco use more effectively. “The statutory warning currently carried on tobacco products is in English, a language that a majority of the population cannot read or understand,” says Ramadoss, who will start a campaign to make workplaces smoke-free this year to protect non-smokers from second-hand smoke.

8. Most people would stop tobacco if they knew what goes into making a cigarette. It has formaldehyde, the chemical used to preserve animals in chemistry labs, cyanamide found in rat poison; and nicotine, which is a powerful insecticide. Studies have shown that bidis are even more harmful than cigarettes.

9. “Tobacco is the second biggest cause of death in the world and kills 5 million people-one in 10 adult deaths each year. If that is not reason enough to stop its use, I don’t know what is,” says Ramadoss.

12. Read the passage given below and answer the questions that follow:

1. Conflict between people takes the forms of assertiveness, aggression, and violence. It is fuelled by many factors, including greed, selfishness, desire, jealousy, envy, fear, hate, and lust for power.

From the perspective of yogic philosophy, these “fuels” for conflict are all caused by a clouding of our perception, called avidya. Because of avidya, we do not recognise our true spiritual kinship with other people, and we are prone to experience those “fuels” of conflict.

2. These “fuels” are widely varied, but have one commonality; experience of any of these emotions or desires is done from an “I” perspective. People who feel these emotions want more (or less) of something for themselves, as compared to what they see in other people. These people do not identify with others, but feel separate from them, left out or isolated. Two powerful tools exist to reduce the effect of these “fuels” within ourselves: cultivating right attitude, and behaving in constructive ways.

3. Some of us feel envious or jealous when we see another who is happy, successful or content. We may feel disgusted or even hatred at the sight of a drifter or a drug addict. In this case, Patanjali’s Yoga Sutras prescribe a change in attitude towards other people, a change that will help us purify our minds and become more peaceful. To become more peaceful, we should practise being pleased when we see another who is happy. We should strive to be compassionate towards those in misery, and joyful to see virtue in another. In cultivating these attitudes, we become more accepting of the world and more peaceful towards others. Non-possessiveness can be practised, as can contentment.

4. Our behaviour-how we act-includes both how we treat others, and how we treat ourselves. To become satisfied in our lives and more peaceful in our treatment of others, we should practise non-violence, truthfulness, and non-stealing, three of the ‘yamas’ from Yoga Sutras. These qualities help us become happier in our lives and less aggressive towards others. Practising meditation is also known to reduce stress and increase happiness.

5. Some people do not want to be less aggressive or happier. They want more power and more control. They don’t want cooperation. They see themselves as separate from others, and responsible for their own success. Their world view assumes that they can and should decide what is proper and that others must conform to their desires. These people will not be swayed by arguments about the happiness that accrues after several years of meditation, or the peace to be found in recognising one’s true Self. They want results, and they want them now. Even these people can accept a yoga practice if it is presented to them in a way they value, which usually means, a ‘physical’ practice. ’

(a) On the basis of your reading of the above passage make notes on it using headings and subheadings. Use recognisable abbreviations, wherever necessary, and give it a suitable title.
(b) Write a summary of the passage in about 80 words based on your notes.
Answer:
(a) To Become Peaceful

1. Causes of conflict:
1.1 greed, selfishness, jeal’sy, fear, hate, lust for power
1.2 according to yoga-these are ‘fuels’
1.3 ‘fuels’ cloud perception-‘avidya’

2. The ‘I’ perspective:
2.1 common among all ‘fuels’
2.2 want things only for themselves
2.3 no ident’cn with others

3. Overcoming the ‘I’ perspective:
3.1. cultivating the ‘I’ not the right atti’de
3.1.1 be pleased for other’s happiness
3.1.2 be compassionate
3.1.3 non-poss’veness & contentment

3.2. behaving in constr’ve ways
3.2.1 non-violence, truthfulness & non-stealing-for others
3.2.2 for ourselves-be less aggressive, practise meditation

4. Yoga can help even those who want power.

Key to abbreviations:

jeal’sy – jealousy
poss’veness – possessiveness
ident’cn – indentification
atti’de – attitude
constr’ve – constructive

(b) Summary
Conflict causes people to be violent. The causes of conflict are jealousy, fear, hate, and lust for power. These are “fuel” and “avidya” in yogic language and cloud our perception.

The ‘fuels’ issue out of an “I” perspective. People want things only for themselves. The ‘I’ perspective can be controlled by (i) cultivating the right attitude, and (ii) behaving in the right way. We feel jealous if we find someone happy. Patanjali’s yoga sutra says we should cultivate the right attitude, be pleased at another’s happiness. We should practise non-violence, truthfulness and non-stealing. Even the aggressive can benefit by ‘yoga practice’.
