Name (sing. stoma = mouth, orifice or opening) for the pores or stomata on leaves of plants and fungi. Gas exchange with the surrounding air takes place through these, especially the supply of carbon dioxide during photosynthesis. The transpiration (evaporation) that takes place through the pores creates a transpiration suction through which water with the nutrients it contains is transported upwards from the roots to the leaves. See also the keywords guttation and humidity.
