双壳类精子发生过程中,细胞核因染色质的浓缩而体积减小,核形状的变化是染色质浓缩时DNA与蛋白质相互作用的结果。在精原细胞形成精子的过程中,一般认为顶体由高尔基体形成,线粒体的数量和分布与细胞的机能状态有关,其变化有一定的规律性,经历了从分散到聚集,从多到少,从小到大,内含物逐渐丰富的变化过程。细胞质大部分在精子形成中成为多余的物质而被抛弃。
During bivalve spermatogenesis, the nucleus decreases in size due to chromatin condensation and changes in nuclear shape are the result of DNA-protein interactions during chromatin condensation. In the process of spermatogonia spermatogenesis, it is generally believed that the acrosome is formed by the Golgi apparatus. The number and distribution of mitochondria are related to the functional status of the cells. The changes have some regularities, from scattered to aggregate, from more to less , From small to large, the gradual enrichment of the content of the process of change. Most of the cytoplasm becomes unnecessary material in the formation of sperm and is discarded.
