Scanning electron micrograph (coloured green) of the upper leaf epidermis of Pisum sativum,the garden pea. The surface is covered with a fuzzy waxy substance which acts as a water repellent. The tiny gaping mouths are stomatal pores,which open & close to regulate the passage of gas between the leaf and the atmosphere. The jigsaw puzzle effect of interlocking pieces corresponds to the arrangement of the epidermal cells; each piece representing a single large cell. Mag: X 100 (35mm).
