Structure of stomata: Stomata are present in leaf epidermis. This diagram is from my Biology notebook. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. 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%. The stomata consist of minute pores called stoma surrounded by a pair of guard cells. Stomata, open and close according to the turgidity of guard cells. When open, stomata allow CO 2 to enter the leaf for synthesis of glucose, and also allow for water, H 2 O, and free oxygen, O 2, to escape. In CAM (Crassulacean Acid Metabolism) plants, stomata open during dark and remain closed during the day. asked Jan 2, 2019 in Class X Science by navnit40 ( -4,939 points) Stomata open and close to allow the intake of carbon dioxide and the discharge of oxygen.

Draw diagram of open and closed stomata. vector art, clipart and stock vectors. The change in turgor, or hydrostatic pressure, within a guard cell pair is the result of the osmotic water flow across the cell walls. 1 Answer. Open 1 Answers 4441 Views. Light intensity required to open the stomata is very low, as compared to the intensity required for photosynthesis. It’s very vital that they do this because this is the very oxygen that we ourselves need to respire! Each stoma remains surrounded by two kidney-shaped or bean-shaped cells called guard cells. 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.
