WebSecondary spermatocytes are haploid cells, smaller than primary spermatocytes, and show coarse chromatin granules and abundant rough endoplasmic reticulum cisternae. 157 … Web9 Apr 2024 · During the phase of meiosis I, a primary spermatocyte is converted into secondary spermatocytes. During the meiosis II phase the cells, in turn, are transformed into (1N). the second mitotic division is quick and so very few secondary spermatocytes can be recognized in histological sections. spermatids and spermatocytes are likely to be larger ...

(a) Identify the human embryonic stages, A … Primary and secondary spermatocytes are formed through the process of spermatocytogenesis. Primary spermatocytes are diploid (2N) cells. After meiosis I, two secondary spermatocytes are formed. Secondary spermatocytes are haploid (N) cells that contain half the number of chromosomes. See more Spermatocytes are a type of male gametocyte in animals. They derive from immature germ cells called spermatogonia.

It begins with a germ cell/primary spermatocyte that is diploid, that undergoes meiosis I turning it into a haploid secondary spermatocyte. The secondary spermatocyte then undergoes meiosis II to turn it into spermatids.
WebThe cell divides unequally, with most of the cellular material and organelles going to one cell, called a secondary oocyte, and only one set of chromosomes and a small amount of cytoplasm going to the other cell. This second cell is called a polar body and usually dies. ... a haploid cell called a secondary spermatocyte ...
