Section of a Leaf


A leaf is comprised of the upper epidermis, palisade mesophyll cells, spongy mesophyll cells, and the lower epidermis. The lower epidermis contains many minute pores for gaseous exchange called stomata. Both the upper and the lower epidermis are covered with a waxy coating cuticle that helps in reducing water loss through leaves.
