Detailed explanation-1: -The mesophyll generally is differentiated into columnar palisade parenchyma cells and irregularly shaped spongy parenchyma cells. The palisade parenchyma tissue usually is located on the upper side of the leaf, and the spongy parenchyma on the lower side.

Detailed explanation-2: -Together, the palisade and spongy layers are known as the mesophyll. The bottom of the leaf is protected by the lower epidermis. Within this are the stomata, which are pores allowing for gas exchange that are regulated by the guard cells.

Detailed explanation-3: -Many plant leaves have two layers of photosynthetic tissue: the palisade and spongy mesophyll. Whereas palisade mesophyll consists of tightly packed columnar cells, the structure of spongy mesophyll is not well characterized and often treated as a random assemblage of irregularly shaped cells.

Detailed explanation-4: -Cuticle: waxy coating over the epidermis. Upper epidermis: epidermal cells located on the upper surface of the leaf. Palisade parenchyma: columnar cells comprising the upper layer of the mesophyll. Spongy parenchyma: irregular cells forming the lower layer of the mesophyll. More items •19-Dec-2021
