Answer:
Stomate, also called stoma, plural stomata or stomas, any of the microscopic openings or pores in the epidermis of leaves and young stems. ... Stomata are generally more numerous on the underside of leaves
Explanation:
Stomata are tiny openings or pores
that enable gaseous exchange. Stomata are usually found in plant leaves, but they can also be found in some stems. When it does not need carbon dioxide for photosynthesis, the plant closes these pores. The stomata in plants are enclosed by bean shaped cells called guard cells. The opening and closing of the pore is regulated by the guard cells. As water flows through them, the guard cells swell allowing the stomatal pore to expand. The pore often closes as the guard cells shrink. Apart from water vapour loss in transpiration, exchange of oxygen and carbon dioxide in the leaf also occurs through these stomata. Stomata are usually open in daytime and close at night.
