Stomata are small pores or opening present in the epidermal cells of leaves. They open during the day and close during night. They take carbon dioxide required during photosynthesis during the day. Also, they release excess water released in the process of respiration during the night along with carbon dioxide. This opening and closing of stomata is controlled by concentration of solutes in the guard cell.
