The spongy mesophyll consists of air spaces that aid in the diffusion of gases. Created by. Sperm Cells (Spermatozoa) There are a number of ways in which a sperm cell is specialised for it's function, these include: 1) The cells are thin and small in order to move more efficiently. Between the cells (palisade cells are generally arranged in a vertical manner to each other beneath the epidermis) are slight separations that allow various materials to flow. In histopathology, a palisade is a single layer of relatively long cells, arranged loosely perpendicular to a surface and parallel to each other.

A palisade cell is traps sunlight with chlorophyll, it is found in the leaf. This refers to the process by which a cell becomes structurally modified to perform specific functions; While cells have a basic outline, they become differentiated to perform specific functions. Beneath the palisade mesophyll are the spongy mesophyll cells, which also perform photosynthesis. Photosynthesis may occur in the spongy mesophyll, but it is a place where gases are exchanged. Spell.
