Detailed explanation-1: -A leaf has the cuticle on top (1) followed by the upper epidermis (2). In the middle is the mesophyll (3 & 4). The lower epidermis (5) includes the stomata (6) and guard cells (7). Leaves have a layer of epidermis on the top and another layer on the bottom.
Detailed explanation-2: -The outermost layer of the leaf is the epidermis. It consists of the upper and lower epidermis, which are present on either side of the leaf. Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). The epidermis aids in the regulation of gas exchange.
Detailed explanation-3: -Lower Epidermis: A protective layer of cells. The lower epidermis produces a waxy cuticle too in some plant species. The lower epidermis contains pores called stomata that allow carbon dioxide and oxygen to move in and out of the plant respectively.
