Photomicrograph of the surface of a fern leaf showing epidermal cells and open stomata, mag. 100x (at 24 x 36 mm). Here the epidermal cells are shaped like puzzle pieces, and the guard cells are green due to the presence of chloroplasts. Each stoma (pore) is defined by a pair of guard cells whose turgor regulates the aperture of the stoma. (c) Herve Conge
