| Abstract: | This paper details an investigation on the anatomical structure of Chorispora tenella and the relationship of adaptability between the structure and the special environment. The outer wall of epidermal cell of stem and leaf has a thicker cuticle. There are a few sto-mates in the epidermis of stem and many stomates in that of leaf. The mesophyll has wel developed palisade tissue. It arranges specially. around the main vein, there is a larger cells of vascular bundle sheath. It contains larger in number chloroplasts, so it belongs to four-carbon plant. |
