Kleinia leaf. Coloured scanning electron micrograph (SEM) of the surface of a leaf of a Kleinia tomentosa plant. The leaf has several close-packed felt-like hairs (brown). These serve to protect against evaporation. At lower centre is a breathing pore or stoma. This regulates the exchange of gases between the leaf and the atmosphere. The Kleinia plant is a stemmed succulent which has a cactus-like appearance. It grows mainly in Africa but is also used as a household plant. Magnification: x175 at 6x7cm size. x280 at 4x5"~LANDSCAPE"
