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. stomata; flag answer . Each stoma remains surrounded by two kidney-shaped or bean-shaped cells called guard cells. In addition to opening and closing the stomata (stomata behavior), plants may exert control over their gas exchange rates by varying stomata density in new leaves when they are produced (such as in the spring or summer). Stomata remain closed during night when there is no photosynthesis and due to accumulation of carbon-dioxide, carbonic acid is formed that causes the pH to be acidic. Stomata open and close to allow the intake of carbon dioxide and the release of oxygen.

(c) stomata and guard cells without nuclei or chloroplasts. As the density of CO 2 retards gradually, the stoma begins to open and it opens gradually lengthwise until the density of CO 2 becomes .01%. (d) stomata but no guard cells or epidermal cells. The guard cells control the opening and closing of stomata. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. New users enjoy 60% OFF. In floating leaves Stomata are confined only on the upper surface of the leaf. Light intensity required to open the stomata is very low, as compared to the intensity required for photosynthesis. (ii) Sayre (1926) observed that stomata open in neutral or alkaline pH, which prevails during day time due to constant removal of carbon-dioxide by photosynthesis.
