Detailed explanation-1: -In the epidermis of leaves, stomata can be observed. Stomata are necessary for gaseous exchange and water vapour loss during transpiration. The bottom side of dicot leaves either has more stomata than the upper side or has stomata just on the lower side.
Detailed explanation-2: -Stomata (singular, “stoma”) are tiny pores through which plants breathe. Stomata are found on the upper and lower sides of leaves, on flower petals, on stems, and on roots.
Detailed explanation-3: -Most plants have stomata on the undersides of leaves. However, water lily leaves have stomata on the upper surface.
Detailed explanation-4: -Stomata are usually present on the lower epidermis. In order to minimize transpiration that occurs with gas exchange, most dicot plants have their stomata on the lower epidermis. On the other hand, monocot plants such as corn can have their stomata on both the top and bottom sides of leaves.
Detailed explanation-5: -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.
