Common sorrel leaf. Coloured scanning electron micrograph (SEM) of the surface of a common sorrel (Rumex acetosa) leaf. Two stomata (leaf pores,round) can be seen at left. Stomata are the site of gaseous exchange in a plant. The opening and closing of the stomata is controlled by semi-circular guard cells,which swell and become turgid to close the openings.
