The cuticle is a waxy layer that covers the upper surface of the leaf, followed by the epidermis, which is a layer of tightly packed cells. Below the epidermis is the palisade mesophyll, which is a layer of elongated cells that contain chloroplasts. The spongy mesophyll is a layer of loosely packed cells that also contain chloroplasts. The lower surface of the leaf is covered by another layer of epidermis, which is followed by the cuticle.
