Answer:
Stomata – Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.

Answer:The guard cells present around the stomata regulate the opening and closing of the stomata.
Explanation:This mechanism is based on the amount of water in the plant . If the plant has enough water, then the guard cells swell thus opening the stomata. And when the plant experiences loss of water , the guard cells close preventing further loss of water.
THUS THE GAURD CELLS REGULATE THE OPENING AND CLOSING OF THE STOMATA.
