Leaf surface of succulent plant Featured January Print

Leaf surface of succulent plant

False colour scanning electron micrograph of leaf surface of a succulent Kalanchoe blossfeldiana, a house plant. Featured are two closed stomata nestled among the epidermal cells.The stomata, pores in the leaf surface, regulate gaseous exchange with the environment. Like many succulents, this one has a Crassulacean acid metabolism, an adaptation 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 at night. The flecks on the surface are wax. Mag: X86 at 35mm. Original is BW print B745/070
