| Abstract: | The spermatogenesis of the clam Paphia undulata was investigated by electronic microscope. Observations of morphological and structural changes of cell, transformation of cell organells, formation of acrosome, sperm morphology in the spermatogenesis process were made submi(?)roscopically. During spermatid differetiation, the main morphologenetic changes were as follows:elongation of nucleus, aggregation and condensation of chromation, acrosome formation and distribution of mitochondria. The spermatozoon belongs to the primitive type, it is characterized by a prominant acrosome, a barrelshaped nucleus, a short middle piece with four rounded mitochondria and a tail flagellum. |
