Thus, the stomata help in the process of transpiration. Loss of water from the stomata creates an upward pull, i.e., suction pull which helps in absorption of water from the roots. Write two functions of stomata. When the stomata are open, they allow carbon dioxide to diffuse into the leaf where it is used for photosynthesis. As epidermal cells, they play an important role in gaseous exchange in and out of plant leaves by regulating the opening and closing of pores known as a stoma. Stomata are thus named because they permit the exchange of gases between the atmosphere and the inside of the leaf. 3.
