Examples
- 1 . spermatogenesis spermatogenesis can be devided into five stagesrspermatogonium , primary spermatocyte , secondary spermatocyte , spermatozon and sperm
精子发生精子发生可分为精原细胞、初级精母细胞、次级精母细胞、精细胞、精子五个阶段。 - The nucleus has two forms at the middle spermatid stage : fibrous one and condensed one . the nucleus extends into the radial arm . the number of organelles keeps increasing until secondary spermatocyte stage
与已有的报导不同的是，我们发现精原细胞分为两类，其中i类精原细胞经过分化形成n类精原细胞。 - According to the changes of the structure of chromatin and the morphology of cell , the process of the typical spermatogenesis of cipangopaludina chinensis can be divided into five stages : spermatogonium , primary spermatocyte , secondary spermatocyte , spermatid and mature sperm
中国圆田螺典型精子发生时，根据染色质和细胞形态的变化，可将其发生分为以下五个时期：精原细胞、初级精母细胞、次级精母细胞、精细胞和成熟精子。 - Nucleoli do not emerge in this process . the number of the organelles increase until secondary spermatocyte stage . mitochondria accumulate together , merging together with lysosomes and golgi bodies at the early spermatid stage , and finally the lamellar structure is formed , which forms the acrosome at last
在精子发生过程中，线粒体、内质网和核糖体逐渐增多，其中线粒体数目在次级精母细胞阶段达到顶峰，并形成线粒体区，精细胞早期核内出现膜性泡结构，同时次级溶酶体与高尔基体大量存在，这些细胞器共同形成片层复合体，并参与顶体的形成。 - Nucleoli exist from spermatocyte stage to early spermatid stage . in this process , the numbers of ribosomes , mitochondrions and endoplasmic reticulums increase until secondary spermatocyte stage , golgi apparatus emerges at the secondary spermatocyte stage , and then , these organelles change into lamellar complex which finally forms the acrosome
核糖体，线粒体和内质网等细胞器数量逐渐增多，到次级精母细胞阶段达到最大，在形成精子的过程中，上述细胞器与高尔基体及膜性泡共同分化或参与形成片层小体，并参与顶体的形成。
