Description
Stoma on a rose leaf. Coloured scanning electron micrograph (SEM) of the lower leaf surface of a Garden Rose Rosa sp., showing an open stoma. Epidermal cells (green) occur around this structure. A stoma (plural stomata) is a tiny pore bordered by two kidney-shaped guard cells. Here the partly open pore is elongated in shape. Guard cells serve to open and close the stoma opening the pore allows gases to be exchanged by leaf tissues during photosynthesis; and closing the pore at night or during dry periods prevents water loss. In the rose, more stomata occur on the underside of leaves. Magnification x850 at 5x7cm size. Magnification x2,500 at 6x4.5inch size.
