In botany, a stoma (plural "stomata"), also called a stomate (plural "stomates") is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange.The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.. Stomata occur on both upper and lower surfaces of leaf, but especially they are confined to the lower surface. Collect. Under normal conditions the stomata remain closed in the absence of light or in night or remain open in the presence of light or in day time. When solute concentration in the guard cells increases, their water potential decreases relative to the surrounding apoplast and water enters the cells. Stomata are small pores or opening present in the epidermal cells of leaves. Normally stomata open when the light strikes the leaf in the morning and close during the night. 3. However, most plants do not have the aforementioned facility and must therefore open and close their stomata during the daytime, in response to changing conditions, such as light intensity, humidity, and carbon dioxide concentration.
