Scanning electron micrograph of the leaf surface of a succulent Kalanchoe blossfeldiana,a house plant. Featured is a closed stoma nestled among the epidermal cells. The stomata (pl. ),pores in the leaf surface,regulate gaseous exchange with the environment. Like many succulents,this one is adapted to hot,arid conditions. The stomata are open at night (reversal of normal),absorbing carbon dioxide & converting it to an organic acid. They close during the day,but continue the process of photosynthesis as usual,using the carbon dioxide collected the night before. The flecks on the surface are wax. Mag: X 1300 (at 10x8 size) | |
