D2 - 4

Solution

Stomata is a pore on the leaves, stems, and other organs, of the plants are meant for control of gaseous exchange during photosynthesis. These pores are formed by pairing of specialized parenchyma cells called guard cells which regulate the size of the opening of the stomata. The opening and closing of stomata depend upon the turgor pressure in the guard cells. When the guard cells are turgid, the stoma opens and when the guard cells lose water, stoma closes.
