Caption: Potato Stomata. Scanning electron micrographs (SEM) of open stomata on a potato leaf (Solanum tuberosum). Stomata are pores that open and close in order to regulate gas exchange in a plant. A stoma comprises a pore, the aperture of which is controlled by a pair of specialized cells known as guard cells. When the guard cells are turgid the stomata are open and when they are flaccid the stomata are closed. Stomata are found mainly on the underside of leaves. Magnification x4300 (x895 at 10cm wide).
