It is important in dicotyledonous plants, because of potential products, pharmaceutical and industrial products in some countries is economically very valuable. Also, this plant has a global spread and has endemic species in many parts of Iran. The vegetative and generative organs were cut and fixed in glycerin and ethanol. The young Root and shoot apical meristem were sampled at different developmental stages. Samples were fixed in FAA and sliced using a microtome. Staining was carried out with Eosin and Haematoxylin. The primary and secondary structures of root, shoot and structure of petiole, leaf, inflorescence, axil, Root and shoot apical meristem showed similarity to dicotyledons, also about male and female flowers of Cannabis sativa L., the sameness of the other angiosperm flowers.
