Answer 2

Answer :-

"Functions of Stomata:

The main function of stomata is to open and close the pores in the leaves for an exchange of gases.

It allows the plant to take in carbon dioxide and give out oxygen for photosynthesis.

Based on the weather conditions, it closes or opens its pores to keep the moisture content developed.

It helps to expel the excess water out from the leaves in the form of water vapour.

Stomata are tiny pores in the plant tissues mainly on the surface of leaves. It is also found in some stems."
