what is stomata
Stomata are found on the leaves of plants. They can either be present on both the sides or just on one side of the leaf.  The structure of the stomata consists of a kidney shaped epidermal cell with an opening in the center which is known as a pore. Inner walls of the guard cells face the aperture and are thicker than the outer layers. Guard cells also have large vacuoles. The cells which surround the guard cells are known as subsidiary or accessory cells.

The most important and major function of stomata is the exchange of gases. In simple terms we can say that the plant takes CO2 from the atmosphere and gives out O2 which is utilized by animals and human beings.
