Teacher wants students to know
What do stomata do? how plants make their food.

Let us know how plants make their food.
Plants make food by combining water
and carbon dioxide gas in the presence
of sunlight and chlorophyll.

Stomata are like windows of a
leaf. They help in the exchange of
gases and water vapour between
the leaf and the surrounding air.

• Plants take water and minerals
through root hair from soil.
• They take carbon dioxide gas
from air through stomata.

• Chlorophyll present in green
leaves takes energy from
sunlight.

• Then, carbon dioxide and water
are combined by taking energy
trapped by chlorophyll to make
food.

• The food made is a kind of
sugar. It is called glucose.
