Simply put, this refers to the process through which the plant takes carbon dioxide from the atmosphere, and gives out oxygen. Role of HCl in stomach. FUNCTION. - 6598638 Answer: Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation. Stoma and stomata are gas exchanging structures found in the leaves and stems of plants. The lower epidermis has more stomata to prevent evaporation. The primary function is to allow gaseous exchange between the plant's internal tissues and the atmosphere. All surfaces of the leaf have some amount of stomata for regulating gas exchange for photosynthesis. It helps in the transpiration of water, i.e., the loss of excess water from the plant. What is the function of stomata? Add your answer and earn points. Related Videos . The remaining function of the light-dependent reaction is to generate the other energy-carrier molecule, NADPH. The exchanges of gases takes place through stomata present on the leaves. Stomata are found on the leaves of plants. Abscisic acid is the plant hormone, which is responsible for dormancy of seeds and inhibition of seeds. Stomata are pores in the plant leaves through which water vapour escapes the plant.
