WebCorrect option is D) In spermatogenesis, spermatozoa are produced by the mitosis and meiosis division of male primordial germ cells. The initial cells are spermatogonia, which produces primary spermatocytes by mitosis. The primary spermatocyte divides meiotically (meiosis I) into two secondary spermatocytes, each secondary spermatocyte divides ... Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called spermatogonial stem cells. The mitotic division of these produces two types of cells. Type A cells replenish the stem cells, an…

WebThus, the primary spermatocyte divides into two haploid daughter cells called secondary spermatocytes. Each secondary spermatocyte now undergoes second maturation division which is a mitotic one. Thus, each secondary spermatocyte gives rise to two spermatids that undergo transformation to form two sperms. chichester yacht club

Is a secondary spermatocyte haploid? - Daily Justnow

Web17 May 2024 · Meiosis has two rounds of cell division: primary spermatocyte to secondary spermatocyte, and then secondary spermatocyte to spermatid. This produces four haploid daughter cells (spermatids). (b) In this electron micrograph of a cross-section of a seminiferous tubule from a rat, the lumen is the light-shaded area in the center of the … WebSecondary spermatocytes are haploid (N) cells that contain half a chromosome. In all animals, males produce spermatocytes, even hermaphrodites such as C. elegans, which exist as males or hermaphrodites. In hermaphroditic C. elegans, sperm production occurs first and is then stored in seminal vesicles. WebSo when the primary spermatocytes differentiate into secondary spermatocytes, they give each of their daughter cells a half of their chromosomes, so now each secondary has 23 … chichester youth connections
