Stomata are tiny pore complexes found in epidermis of leaves and other soft aerial parts. The lower surface of a dorsiventral (often dicotyledonous) leaf has a greater number of stomata than the outer surface, while in an isobilateral (often monocotyledonous) leaf, stomata are about equal in number on both surfaces.
