How does the climate differ in these habitats?
Name some animals that exist in these habitats.
Can an animal survive if it is shifted from one habitat to another contrasting habitat?
Answer:
In terrestrial habitat, the temperature is more. In water habitat, the temperature is less.

Answer:
Activities to be done by the students themselves

Samacheer Kalvi 6th Science The Cell Intext Activities

Activity 1

Aim:
To observe the structure of a single cell (Hen’s egg).

Materials Needed: A hen’s egg and a plate.

Method: Crack the shell and break open the egg in a plate.

Observation: The egg has a yellow part and a transparent part surrounding it. The white transparent part (albumin) is jelly-like and represents the cell’s cytoplasm, while the yellow part (yolk) is thicker and represents the cell’s nucleus. On the internal side of the shell can be seen a thin membrane- like structure, which represents the cell membrane.

Activity 2

Aim: To observe onion peel cells under a microscope

Materials Required: Glass slide, cover slip, onion, iodine solution, knife and microscope.

Procedure: Take an onion and cut it into two halves along its length. Take out one of its fleshy leaves. With the help of a pair of forceps, remove a transparent, thin peel from the inner surface of the leaf. Take a glass slide and put a drop of water at the centre. Place the peel on the drop of water. Pour a drop of iodine solution on the peel. Now place a cover slip over the material. Observe under the microscope.

Observation: You will be able to see rectangular cells of the onion peel, with a nucleus in each of them.

Activity 3

Aim: To rectify the variation between 2-D shape and 3-D shape.

Material req uired: Polythene bag, water, marble ball (golli gundu)

Procedure: Take a polythene bag with water. Put a marble ball into the polythene bag. Then draw a picture in your note book about this task. If you draw a picture in round shape. It will be called 2-Dimenstional picture. If you draw a picture in spherical shape it is called 3-dimenstional.

Result: Now you understand your misconceptions. So the animal cells are spherical in shape and structure, not in a round shape.

Picto Grammar

Noun And Adjective Types

Nouns are names of people, places, animals or things.
Example : Geetha went to the market to buy some fruits.
In the given sentence, the words in italics are nouns.

kinds of Nouns

1. Common Nouns : A common noun is a name which does not point out any particular person, animal, place or thing, but is common to all persons or things or the same class or kind. Some examples of common nouns are school, book, teacher, city, girl, men, boys, girls, pupils, etc.

2. Proper Nouns : A proper noun is a particular name of a person, animal or place. It always begins with a capital letter. For example, Vasu is a Proper Noun, for it is the name of a particular boy. Similarly, Lucknow is a Proper Noun for it is the name of a particular place.

3. Collective Nouns : A collective noun represents the name of a collection of persons or things which is considered as one complete whole. Following are some collective nouns :

4. Abstract Nouns : An abstract noun is the name of something, which we can neither see nor touch, but we can only think of. For example, fear, bravery, love, health, curiosity, kindness, etc.

Abstract nouns can be formed from different words by adding suffixes.

from common nouns:

enemy – enmity
patient – patience
poet – poetry
child – childhood
student – study
friend – friendship

decide – desision
punish – punishment
act – action

Countable And Uncountable Nouns

Generally, most of the common and collective nouns are countable. For example, girls, boys, keys, birds, etc. can be counted.

Proper nouns like Kolkata, Suraj, India are names of particular places or persons. There is only one of their kind so, they are uncountable.

Some common nouns that name materials like wood, iron, milk, silk, etc. are uncountable.

Sugar, Rice, Wheat, etc. are also uncountable.

Abstract nouns like pride, beauty, hardness, health, etc. cannot be counted.

A countable noun has a plural, however, an uncountable noun does not have one. For example, the plural of dog is dogs, the plural of flower is flowers but we cannot write prides, healths, etc.

Countables may be used with words like a one, two, few, a few, many, etc. For example, a table, one boy, a few mangoes, many people, etc.

Uncountables cannot be used with these words. We cannot say, one milk, a few happiness or a water. We can use words like little (a little), much, etc. with uncountables. For examples, a little milk, much help.

A Visitor from Distant Lands Summary

This lesson is about native and imported vegetables. One-day, when Amma served potato curry, Mani’s favourite dish, he refused. He told that potato is a foreign vegetable and he would like locally grown food. Tomatoes, pine-apple, com, ladies fingers were other foreign vegetables. When Mani asked how these vegetables reached India, his father explained that merchants brought them by sea. The merchants came to India to take spices and in turn Portuguese gave us potatoes. The chillies were grown in south America where Columbus discovered it and later it reached India from Portuguese. Before chillies, we used pepper in cooking.
