Detailed explanation-1: -Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.
Detailed explanation-2: -Closing and opening of stomata help in the exchange of gases between the plant its surrounding. It facilitates the entry of carbon dioxide into the plant and removal of oxygen from the plant. Carbon dioxide that enters the plant through stomata is a primary raw material for photosynthesis.
Detailed explanation-3: -Its prime function is to exchange the gases by closing and opening the pores in the leaves. It assists in eradicating excess water from the leaves. It removes oxygen and takes in carbon dioxide at the time of photosynthesis.
