Out of the four layers, which cells of are the most active for protein synthesis:: (A) Spinous cell., (B) Basal cell., (C) Granular cell., (D) Corneum cell.
Answer is A. The spinous (prickle) cells resemble a cocklebur or sticker that has each spine ending at a desmosome. Of the four layers, the spinous cells are the most active in protein synthesis. These cells synthesize additional proteins that differ from those made in the basal cells.
