Draw a well-labeled diagram of stomata.


Extra information:

Stomata are the tiny openings, present in the epidermis of leaves, stems, and other organs, to allow the exchange of gases.

A stoma, also called a stomate is a pore/minute openings, found in the epidermis of leaves, stems, and other organs, that facilitate gas exchange.

The stomatal pore is guarded by two kidney bean-shaped cells known as guard cell. It helps in the closing and opening of the stomatal pore.

The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.

The main functions of stomata are:

1) They allow the exchange of gases from the surrounding medium.

Usually, carbon dioxide is taken up and oxygen is released.

2) From stomata, transpiration takes place that is the loss of excess water from the aerial parts of the plant.
