Each and every stoma in surrounded by a pair of kidney shaped guard cells. Each and every guard cell is a modified epidermal cell exhibiting a prominent nucleus, cytoplasm and plastids. Wall of the guard cell is differentially thickened. The inner wall of all guard cell facing the stoma is concave and is rigid and thick. The outer wall is convex and is thin and elastic.
