Describe the process of Spermatogenesis
Answers
Answer:
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. ... The spermatids are transformed into spermatozoa (sperm) by the process of spermiogenesis. These develop into mature spermatozoa, also known as sperm cells.
Answer:
Spermatogenesis is the process of the production of sperms from the immature male germ cells. It starts at puberty and usually continues uninterrupted until death, although a slight decrease in the quantity of sperm is seen with increase in age.
Stage 1: The Diploid spermatogonia is situated in the seminiferous tubules which include twice the total number of chromosomes. This replicates mitotically in interphase before the method of meiosis 1 to create 46 pairs of sister chromatids.
Stage 2: In this, the chromatids allow the exchange of genetic information through the synapsis process. It is done before dividing into haploid spermatocytes through meiosis.
Stage 3: In this division, the new two daughter cells will further divide into 4 spermatids, having unique chromosomes that are approximately half in number to the original spermatogonium.
Stage 4: In this stage, the cells move from the lumen of the testes to the epididymis. They get mature and developed into four sperm cells with the growth of microtubules on the centrioles to develop an axoneme. The remaining centrioles elongate and develop into sperm tail.
