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: -Answer and Explanation: Most stomata are located on the bottom of leaves, or the ventral portion. The main reason for this is to control water loss from evaporation, as water can be lost when the stomata open to allow gas exchange. The more sunlight hits an area, the more water it will lose.
Detailed explanation-3: -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-4: -Stomata are found mainly on the lower surface of the leaf to reduce water loss by transpiration.
