The upper and lower layers of the leaf are formed by epidermal cells, with a waxy cuticle covering the outer surface. The cuticle protects the epidermis and reduces water loss. Below the upper epidermis are the palisade mesophyll cells, the primary site of photosynthesis in the leaf. Below the palisade layer is the spongy mesophyll layer, consisting of loosely packed photosynthetic cells. The loose arrange­ment of the spongy mesophyll allows for high uptake of carbon dioxide and release of oxygen...
