Stoma (singular), usually called as Stomata (plural), is an opening found the leaf epidermis and stem epidermis used for gaseous exchange in plants.In Dicotyledons, more stomata is present in the lower epidermis of leaves than in the upper epidermis.On the other hand, Monocotyledons have same number of stomata on their upper epidermis as well as in the lower epidermis. Generally stomata are open during the day and close at night. Light intensity required to open the stomata is very low, as compared to the intensity required for photosynthesis.
