Roots
- Contain seeds.
- Make fruit.
- Fixes the plant to the ground.[✓]

- Make food food for that plant.
- Carry water to the leaves.
Fruits
- Contain seeds.[✓]
- Fixes the plant to the ground.
- Make food for the plant.
- Carry water to the leaves.
Stem

- Carries water to the leaves. [✓]
Leaves

- Makes food for the plant. [✓]
Let’s
do an experiment!
- Fill a beaker about three-quarters with water.
- Add drops of food colour till the colour of water turns dark (at least
five drops). Stir until the colour is even.
- Cut about 2.5 cm off the bottom of a white rose stalk with the knife
and place it in the beaker with the leaves sticking up.
Let
the rose stalk sit overnight in the coloured water. Now write your observations
based on it.
- What did you observe the next day?
Ans- The
observed that the white rose became coloured.
2.
Your teacher will cut some portion of the rose stalk.
Draw and label what you observe in the space provided below.
Q. Forests are being cut to build townships. Write
your views on this.
Forests purify air and bring rain. Cutting of forests cause
climate change.
Q. What is the function of the seed?
Ans- Seed germinates and gives rise to the new plant.
Section-C Creative Thinking
Skills
One day, the leaves and roots of the plant had a
fight. Each thought that it was more important than the other. They want your
opinion in this matter.
Who is more important?
Leaves [ ]
Roots [ ]
Both
[✓]
Give reasons for your choice.
Roots fix the plant to the ground and absorb water from soil.
Leaves make food using the same water. Therefore, both are important.
Do it yourself
Take a leaf of your choice (preferably is
smaller, in size than the box given below). Put it under a paper and softly
rub your pencil over it. The wheels and leaf edges will appear on the paper.
Fill in the blanks with the options given
below:
|
green, sunlight, chlorophyll, red, air,
water
|
1-
The colour of the leaf is mostly green but some
are red in colour.
2-
Leaves the need sunlight, air, water and chlorophyll
to make food.
