Sycamore Leaf Stoma (Acer pseudoplatanus)
Scanning electron micrograph (sem) of a sycamore leaf stoma (Acer pseudoplatanus). 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. This micrograph also clearly shows the wax platelets that cover the leaves. Magnification x6100 (x1500 at 10cm wide)
