There are small openings on the lower surface of the leaves. These pores are called stomata. These openings are surrounded by guard cells.

FUNCTIONS OF STOMATA:

1. It helps in the transpiration of water, i.e., the loss of excess water from the plant.

2. Loss of water from the stomata creates an upward pull, i.e., suction pull which helps in absorption of water from the roots.

3. Stomata are responsible for the interchange of gases for respiration and photosynthesis.

4. The stomata allow for the loss of excess water in the form of water vapour, which also allows cooling.
