Stomata are small pores present in the epidermis of leaves. They regulate the process of transpiration and gaseous exchange. The stomatal pore is enclosed between two bean-shaped guard cells. The inner walls of guard cells are thick, while the outer walls are thin. The guard cells are surrounded by subsidiary cells. These are the specialized epidermal cells present around the guard cells. The pores, the guard cells and the subsidiary cells together constitute the stomatal apparatus.
