explain the process of spermatogenesis in human?
Answers
Answer:
it is a formation of haploid microscopic and functional male gamete called sperm
Explanation:
its divided into 2 parts
1- formation of spermatid
A-multiplicative or mitotic phase
it involves rapid mitotic div of 2n primary germ cells present in germ cells of seminiferous tubules of testes....
this forms large number of diploid and rounded sperm mother cells called spermatogonia....
some spermatogonia acts as stem cells and go on dividing and adsing new cells by repeatwd mitotic div ....but some spermatogonia move imwars and entets in growth phase( TYPE B spermatogonia)
2- growth phase
Explanation:
Spermatogenesis is the process of the production of sperms from the immature germ cells in males. It takes place in seminiferous tubules present inside the testes. During spermatogenesis, a diploid spermatogonium (male germ cell) increases its size to form a diploid primary spermatocyte. This diploid primary spermatocyte undergoes first meiotic division (meiosis I), which is a reductional division to form two equal haploid secondary spermatocytes. Each secondary spermatocyte then undergoes second meiotic division (meiosis II) to form two equal haploid spermatids. Hence, a diploid spermatogonium produces four haploid spermatids. These spermatids are transformed into spermatozoa (sperm) by the process called spermiogenesis.
