Photomicrograph with DIC of the lower side of a holly leaf showing a closed stoma, transverse section, mag. 100x (at 24 x 36 mm). Shown are the lower epidermis (top) with a stoma and spongy mesophyll (bottom). The stoma is defined by a pairof guard cells whose turgor regulates the aperture of the s toma. A closed stoma prevents gas exchange. (c) Herve Conge
