On the basis of morphological features, 10 consecutive structural phases of spermatids were identified in Chara vulgaris spermiogenesis. They were schematically presented. In early and middle spermiogenesis, i.e. during the period preceding formation of fibrillar structure of mature spermatozoid nucleus, a slight remodelling of chromatin, accompanied by proplastid transformation into an amyloplast as well as by development of 2 flagella and a microtubular manchette, is observed.
