Scanning electron micrograph (sem) of a stoma of a Smoke Bush (Cotinus coggygria),sometimes known as a Flame Bush. 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 specialised cells known as guard cells. These cells swell to close the pore and shrink to open it. Stomata are found mainly on the underside of leaves. Magnification x 11550 (x2842 at 10cm wide) | |
