Explanation:

What is Stomata?

Stomata are the tiny openings present on the epidermis of leaves. We can see stomata under the light microscope. In some of the plants, stomata are present on stems and other parts of plants. Stomata play an important role in gaseous exchange and photosynthesis. They control by transpiration rate by opening and closing.

Functions of Stomata

The main functions of stomata are:

1. Gaseous exchange- Stomatal opening and closure help in the gaseous exchange between the plant and surrounding.

2. It helps in transpiration and removal of excess water in the form of water vapour.

3. Stomatal closure at night prevents water from escaping through pores.

4. It maintains the moisture balance according to weather by opening and closing.

5.Stomata facilitate carbon dioxide uptake and release of oxygen during the process of photosynthesis.
