Plant stomata. Light micrograph of stomata (dark blue holes) on the surface of a plant. Stomata are pores that regulate the exchange of gases and water vapour into and out of the plant. Guard cells (white) either side of the opening regulate this by expanding and deflating in response to osmotic pressure. When they expand, this causes them to move apart from one another and open the pore. This image was created using an epithelial peel to chemically remove the top layer of the leaf. Magnification: x100 when printed 10 centimetres wide.
