Potato leaf. Coloured scanning electron micrograph (SEM) of a transverse section of a potato leaf (Solanum tuberosum). The upper and lower surfaces of the leaf are covered in a single layer of closely packed cells called the epidermis. Below the upper epidermis is a layer of palisade parenchyma cells containing many chloroplasts. Beneath this layer is the spongy mesophyll which has large intracellular spaces for gaseous exchange. At the bottom is the lower epidermis,a single layer of closely packed cells where the stomata control gas exchange within the spongy mesophyll. Magnification x1260 (x262 at 10cm wide) | |
