When we compare one person or thing with another, we use a comparative degree.

  • The Amazon is longer than the Ganga.
  • Amita is shorter than Neha.

When comparing more things using a comparative adjective, we use the conjunction than in the sentence. While comparing more than two things, we use the superlative degree.

  • The Nile is the longest river in the world.

Question 4.
What are the functions of blood?
Answer:
The functions of blood are:

  • It transports oxygen to all parts of the body from the lungs.
  • It transports the digested food to all parts of the body from the small intestine.

Transportation in Animals and Plants Class 7 Extra Questions Long Answer Type

Question 1.
Write the structures and functions of blood vessels.
Answer:
The structures and functions of blood vessels are given as follows:
Arteries:
Structure: Arteries have thick elastic wall because they carry blood from the heart at a high pressure to other parts of the body.
Function: They carry oxygen-rich blood from the heart to all parts of the body.

Veins:
Structure: They have thin walls comparatively to arteries because the blood flows with less pressure. Rather they have valves which prevents back flow of blood.
Function: They carry carbon dioxide-rich blood from all parts of the body to the heart.

Capillaries:
Structure: These are very thin blood vessels, having walls one cell thick.
Function: Across the thin wall of the capillaries, the exchange of gases and nutrients take place between the blood and the surrounding cells.

Question 2.
Explain the working of heart.
Answer:

  1. Deoxygenated blood from all parts of the body enters the right chamber of the heart called right artium or auricle through superior and inferior vena cava.
  2. As the atrium contracts deoxygenated blood flows from right atrium to right ventricle through tricupsid valve.
  3. When ventricle is full tricupsid valve shuts to prevent backflow of blood into atrium.
  4. The ventricle then contracts blood into pulmonary artery to reach the lungs where it get oxygenated.
  5. Oxygenated blood then returns to the left atrium of heart through pulmonary veins.
  6. As the atrium contracts, oxygenated blood flows from left atrium to left ventricle through mirtal valve.
  7. And when ventricle contracts, blood leaves the heart through aortic valve to the arteries. Arteries circulate blood throughout the body.

Question 3.

Answer:
Transportation in Animals and Plants Class 7 Extra Questions and Answers Science Chapter 11 1

Question 4.
What are the various components of blood. Write function of each component.
Answer:
Blood has four main components, i.e., plasma, red blood cells, white blood cells and platelets. Function of various components are:

  1. Plasma: Plasma is the watery component of blood. It suspends other components of blood. It contain many important dissolved substances, such as protein, electrolytes, nutrients, gases and waste products. It maintain the exact pressure of the blood.
  2. Red blood cells: RBC contain haemoglobin protein, whose main function is to carry oxygen to all parts of the body and to bring carbon dioxide to the lungs.
  3. White blood cells: Main function of WBC is to fight against infections diseases and foreign invaders.
  4. Platelets: It helps in clotting of blood during injuries and thus, prevent excess loss of blood from our body.

Question 5.
Explain the excretion in birds, fishes, lizards, dogs and humans.
Answer:
The way of the elimination of waste products from the body of animals depends on the availability of water. Animals like birds and lizards excrete a white coloured, semi-solid product, known as uric acid. Aquatic animals (like fish) excrete the waste materials (i.e., ammonia) in the gaseous form which directly dissolve with water. Dogs and human beings excretes urea.

Question 6.
Explain human circulatory system with a well labelled diagram.
Answer:
Circulatory system is the life support system of our body that provides our body cells with nutrients and oxygen. It takes away waste product from the body cells. Our circulatory system comprises of the heart, blood, blood vessels and lungs.

  1. Blood is the fluid that carries oxygen and nutrients to various parts of the body and takes away wastes and carbon dioxide from the cell for elimination.
  2. Blood vessels comprises of arteries, veins and Capillaries. Arteries carry oxygen-rich blood from the heart to various parts of the body. Capillaries are single-walled vessels which exchange gases and nutrients from the cells.
  3. Veins carry carbon dioxide-rich blood from different parts of the body to the heart.
  4. Heart is a muscular organ with four chambers which pumps blood throughout the body. It pumps carbon dioxide-rich blood to the lungs for purification.
  5. When it receives oxygen-rich blood from the lungs it again pump this blood to arteries for transportation to various body parts.
  6. Lungs helps in exchange of gases between air we breathe in and the blood. It helps in elimination of carbon dioxide from blood and making it rich in oxygen content.

Transportation in Animals and Plants Class 7 Extra Questions HOTS

Question 1.
Which feature of heart does not allow mixing of oxygen-rich blood with carbon dioxide-rich blood?
Answer:
Heart is divided into four chambers and are protected with valves which prevent their backflow. Thus, these features prevent mixing of oxygen-rich blood with carbon-dioxide rich blood.

Question 2.
Why do doctor often holds our wrist when we go for a check up?
Answer:
Doctor holds our wrist to count our pulse rate and to check whether it is normal or not.

Question 3.
Why wall of right ventricle is thinner than that of the left ventricle?
Answer:
This is because the left ventricle has to pump blood all the way around the body, but the right ventricle only has to pump it to the lungs.

Question 4.
What will happen if oxygenated and deoxygenated blood gets mixed?
Answer:
Mixing of oxygenated blood with deoxygenated blood will lead to less oxygen supply to the cells. Under oxygen deficient condition, cells will not perform normally which may adversely affect the organism as a whole.

Question 5.
Does artery always carries oxygen-rich blood?
Answer:
No. Pulmonary artery carries carbon dioxide-rich blood from heart to the lungs.

Question 6.
Sponges and Hydra do not posses any circulatory system. How nutrients and oxygen is transported inside their body?
Answer:
The water in which sponges and Hydra live brings food and oxygen as it enters their bodies. The water also carries away waste material and carbon dioxide as it moves out. Thus, these animals do not need a circulatory system.

Question 7.
Water from soil moves inside the root cell but never comes out from root cell to soil. Why?
Answer:
Water always move from a region of its higher concentration to a region of its lower concentration. This process is called osmosis. Concentration of water is more in the soil compared to its concentration inside the root cell, so it move from soil to the root cell and not from root cell to the soil.

Pronouns are words we use to replace nouns in order to avoid their repetition. The noun that a pronoun replaces is called an antecedent. There are different kinds of pronouns.

Fundamentals:
A pronoun is a word used in place of a noun, which can be a person, place, animal or a thing. Personal, Reflexive, Demonstrative, Interrogative, Possessive are the different types of pronouns.

Personal Pronouns:
A pronoun is a word used in place of a noun, which can be a person, place, animal or a thing. The pronoun must agree in number with the noun that it replaces. If the noun is in the singular form, the pronoun must also be in the singular form, or if it is in plural form, the pronoun must also be in the plural form.
Examples:

  • Singular: The boy is playing with his puppet. He has a glove puppet.
  • Plural: The boys are playing with their puppets.
    They have puppets of various colours:

    • Personal Pronouns have three persons.
    • The person who is speaking is called the first person, i.e. I, my, me, we, our, us.
    • The one spoken to is called the second person, i.e. you, your, yours.
    • The one spoken about is called the third person, i.e. he, she, it, they, their, them.

The pronoun must agree with the noun in gender that it represents. If the noun is feminine, the pronoun too must be feminine. Likewise, if the noun is masculine, the pronoun must be also masculine.
Examples:

  • Masculine: Jyoti has a boyfriend. He comes across as a bit of a bore to her.
  • Feminine: Sunny’s sister loves to eat green vegetables. She eats it almost every day.
  • Neuter: We have an old kitchen table. It has a broken leg.

A reflexive pronoun is used when the object of a sentence is the same as the subject. They either end in -self, as in the singular form, or -selves as in the plural form.

The singular reflexive pronouns are: myself, yourself, himself, herself, itself.
Plural reflexive pronouns include: ourselves, yourselves, themselves.
Emphatic Pronouns: When words like myself, yourself, himself, itself, etc. are used for the sake of emphasis they are called emphatic pronouns.
Examples:

  • I myself wrote this poem.
  • They themselves admitted it.
  • The announcement was made by the Principal himself.

It is usually placed immediately after the noun or pronoun which they emphasize. Sometimes, they follow at a distance.
Examples::

  • He said to himself.

Demonstrative pronoun is used to point out specific person, place, thing or idea. This/that/these/those are demonstrative pronouns.
Examples::

  • Is this my chair?

Interrogative Pronoun introduces a question.
Examples:

  • Who, What, When, etc. Examples:: Who was Graham Bell?

Possessive pronouns are used to talk about things that belong to people. The words mine, yours, his, hers, ours and theirs are possessive pronouns. We do not use an apostrophe with possessive pronouns.
Examples:

  • This mobile is mine.
  • Have you lost yours, Pankaj?
  • This glass is mine and that one is his.
  • Sarika has lost her cat. Is this cat hers?

Here is a table to help you remember which possessive pronouns to use with singular and plural pronouns.

Singular Personal PronounsPossessive Pronouns
I, meMine
YouYours
He, himHis
She, herHers
Plural Personal PronounsPossessive Pronouns
We, usOurs
YouYours
They, themTheirs

Indefinite Pronouns:
An indefinite pronoun does not refer directly to any other word. Most indefinite pronouns express the idea of quantity. All, each, most, other, another, either, neither, several, any, everybody, nobody, some, anybody, everyone, none, somebody, anyone, few, no, one, someone, both, many, one, are some indefinite pronouns.

Relative Pronouns:
These are used to refer back to a noun or a pronoun in a sentence. Who, whom, whose, which, that are relative pronouns.
Examples::

  • My mother is a teacher. She writes stories for the children.
  • My mother is a teacher who writes stories for the children.

Distributive Pronouns:
Each, either and neither are called distributive pronouns because they refer to persons or things one at a time. Note that a distributive pronoun is always singular and as such it should be followed by a singular noun and verb.
Examples::

  • Each boy was given a prize.
  • Either road leads to the railway station.
  • Neither accusation is true
  • Each new day is different. (NOT Each new days are different.)
  • Either girl can do that. (NOT Either girls can do that.)
  • Neither answer is correct. (NOT Neither answers is correct.) (NOT Neither answers are correct.)
  • Each of, neither ©f and either of are followed by plural nouns and singular verbs. Each of the answers are correct. (NOT Each of the answer is correct.)
  • Neither of the girls can do that. (NOT Either of the girl can do that.)
  • Either and neither should be used only when talking about two persons or things.
  • When more than two persons or things are spoken of, any, no one or none should be used.
  • None of the three answers is correct. (NOT Neither of the three answers is correct.)
  • We invited several friends, but none came. (NOT … but neither came.)
  • You can take any of the three shirts. (NOT You can take either of the three shirts.)

This grammar section explains English Grammar in a clear and simple way. There are example sentences to show how the language is used. You can also visit the most accurate and elaborate NCERT Solutions for Class 7 English. Every question of the textbook has been answered here.

Types of Noun

Common noun:

It does not name any particular person, place or a thing. It speaks in general about persons, places or things of the same kind.
Examples:

  • The boy kicked the ball.
  • The bag is lying under the table.

Proper noun:
It names a particular person, place or a thing.
Examples:

  • Virat Kohli lives in India.
  • Barack Obama lives in America.

Concrete noun:
A noun that denotes a material object rather than an abstract quality, state or action.
Examples:

  • Dog, building, tree

Abstract noun:
It names a feeling or a state of being which has no form or shape and which cannot be seen or touched, but whose existence we can recognise.
Examples:

  • A thing of beauty is a joy forever.
  • Perseverance leads to success.

Collective noun:
It names a group or a collection of people or things taken together and treated as one.
Examples:

  • Radhika gave me a bunch of flowers.
  • The pride of lions was asleep.

Countable noun:
A noun which can be counted is called a countable noun. So countable nouns can either be singular or plural. Some common nouns and collective nouns belong to this category.
Examples:

  • one girl, many girls, a herd of elephants

Uncountable noun:
A noun which cannot be counted is called an uncountable noun.
So it is neither singular nor plural. Some common nouns and abstract nouns belong to this category.
Examples:

  • some rice, much happiness

Gender Nouns:
The Gender of a noun indicates whether it is male or female.
For Examples::

  • boy, girl, hero, heroine, lion, lioness, etc.
  • A noun that denotes a male is called Masculine Gender.

Masculine nouns are the words for men, boys and male animals.
Examples::

  • Boy – Lion – Bull – Dog

A noun that denotes a female is called Feminine Gender. Feminine nouns are the words for women, girls and female animal.
Examples:

  • Book – Pen – Room Tree

Number Nouns:
There are two types of nouns on the basis of number: Singular Noun and Plural Noun

Singular Noun:
When we speak about one person and one thing, we use the noun in singular form. Single means one.
Examples:

  • a. A man is walking within the premises.
  • b. A group of cows is called a herd.
  • c. A monkey can climb trees faster than you.
  • d. Temple is the worshipping place of Hindus.
  • e. This table is made of wood.

In these sentences, the nouns- man, group, monkey, temple and table are in singular forms.

Plural Noun:
When we speak about more than one person or thing, we use the noun in plural form.
Examples:

  • a. Few women are standing in the temple.
  • b. The groups of cows, coming back to their sheds, are not milch cows.
  • c. These tables are made of plastic.
  • d. Children should be given proper guidance.
  • e. Keep the guns in a safe place.

In these sentences, the words women, groups, tables, children and guns are plural- nouns.

Possessive Case:
When a noun or a pronoun is used to show ownership or possession, authority, origin, kind etc., it is called Possessive Case.
Examples:

  • This is Rohit’s bike.

When the noun is Singular, the Possessive Case is formed by adding apostrophe S (‘S) at the end and when the noun is plural and end in ‘S’, we add apostrophe after ‘S’ (‘S).
Examples:

SingularPossessivePluralPossessive
BoyBoy’sBoysBoys’
BookBook’sBooksBooks’
GirlGirl’sGirlsGirls’
ManMan’sMenMen’s
OurOursWomenWomen’s
MyMineParentsParents’
YouYours
8080s’
20092009’s
ItIts
WhoWhose

Apostrophe or no apostrophe if the noun ends in ‘s’.
When a proper noun ends in s, the possessive form can be made either by adding an apostrophe and an ‘s’ or only an apostrophe.
Examples:

  • This is a portrait of the King Charles’s wife. / This is a portrait of the King Charles’ wife.
  • My uncle James’s factory was burnt down last night. / My uncle, James’ factory was burnt down last night.

Two possessive nouns one after the other
Sometimes, two possessive nouns appearing one after the other may be necessary to indicate double ownership.
Examples:

  • She is Rohit’s brother’s girlfriend.
  • This is Sonika’s father’s car.

Apostrophe indicates joint ownership
When two nouns are joint owners of something, only the second noun is in the possessive form i.e. an apostrophe and ‘s’ is added at the end of second noun.
Examples:

  • On that hill is Jack and Jill’s house. (The house belongs to both Jack and Jill.)
  • Sonali and Sonali’s mother are doctors.

Compound possessive nouns
If it is a hyphenated compound noun, add the apostrophe s (‘s) to the last word.
Examples:

  • My brother-in-law’s car hit a truck the other day.
