A re-light optical research spermatogenesis Picea abies (L.) Karst shows that contrary to the assertions Fergusson (1901) and Camefort (1978) sperm spruce are cells: each core is surrounded by a private limited cytoplasm plasma membrane. At the same time, this study clarifies our opinion expressed in the together published work on this issue (Moszkowicz, Chebotari, 1986). It was also found that the sperm from plazmogenez spruce is completed by the end of the programmed phase of fertilization, ie, by the mioment of the contact with the pollen tube ovule nucellus. Reproached position of the sperm nuclei for the entire period of growth of the pollen tube, creates a single view of the cytoplasm, but large size of male gametophyte spruce and careful microscopic analysis of the same drugs had allowed to clarify the phylogenetic question.
