What is the function of the stomata?

The stomata controls the flow of gases in and out of the leaves.

Explanation:

The opening and closing of the stomata controls gas flow in leaves. This controls is necessary to prevent excessive loss of water as vapour from the plant body via transpiration. Usually stomata opens in the day and closes in the night. Each stoma or stomatal wall is flanked by two bean-shaped guard cells, the only epidermal cells with chloroplasts. The wall of the guard cells next to the pore are thicker than those adjacent to the epidermal cells. Here,,the thicker wall cannot stretch as much as the thinner walls.
