Stomata are usually found on the underside of a leaf to reduce excess water loss, and they're surrounded by guard cells that open and close the pores.Though stomata release water, their main purpose is to exchange gases.imilar to the sweat glands on your skin, plants have openings on their leaves that allow water to escape, called stomata (singular: stoma).

If it is a submerged leaf, no stomata will be present on either side. In botany, a stoma (also stomate; plural stomata) is a tiny opening or pore, found mostly on the under-surface (epidermis) of a plant leaf, and used for gas exchange.The pore is formed by a pair of specialized parenchyma cells known as guard cells which are responsible for regulating the size of the opening. years ago.

Locating fewer stomata on the upper epidermis can then prevent excess water loss.
