Explanation: 

Detailed explanation-1: -Stomata are tiny pores or openings on the green parts of a plant, especially the leaves. They enable gaseous exchange through them. They also are responsible for transpiration to occur in plants. Stomata are surrounded by kidney-shaped guard cells, which regulate and control their opening and closing.

Detailed explanation-2: -Stomata, turgor-driven cellular valves on the plant aerial epidermis, serve as an interface between a plant and its environment. By dynamically adjusting stomatal pore apertures, stomata facilitate gas exchange for photosynthesis while minimizing water loss via transpiration.

Detailed explanation-3: -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.
