why is the stomata located in the epidermis
If it is a submerged leaf, no stomata will be present on either side. In botany, a stoma (also stomate; plural stomata) is a tiny opening or pore, found mostly on the under-surface (epidermis) of a plant leaf, and used for gas exchange.The pore is formed by a pair of specialized parenchyma cells known as guard cells which are responsible for regulating the size of the opening. years ago. Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. As these leaves are held horizontally, upper epidermis is directly illuminated. Locating fewer stomata on the upper epidermis can then prevent excess water loss.
