Question

The correct sequence of spermatogenesis stage leading to the formation of sperms in a the mature, human testis is
A. Spermatogonia →spermatocyte→spermatid→sperms
B. spermatid→spermatocyte→spermatogonia→sperms
C. spermatogonia→spermatid→spermatocyte→sperms
D. spermatocyte→spermatogonia→spermatid→sperms

Answer 1

Hint: Spermatogenesis is the cycle by which haploid spermatozoa are formed. They are developed from germ cells. These germ cells are developed in the seminiferous tubules of the testis. This cycle begins with the mitotic division of the immature microorganisms found near the cellar layer of the tubules. These cells are called spermatogonial undifferentiated organisms.

Complete step by step answer: 

In human males, the early-stage germ cells partition mitotically and produce spermatogonia. A portion of the spermatogonia develops into enormous essential spermatocytes. Every essential spermatocyte goes through first development. A division which is a reductional (meiotic) one. Accordingly, the essential spermatocyte separates into two haploid daughter cells called auxiliary spermatocytes. Every auxiliary spermatocyte presently goes through a second development division which is a mitotic one. Accordingly, every auxiliary spermatocyte offers to ascend to two spermatids that go through a change to shape two sperms. By and large, two auxiliary spermatocytes offer ascent to four sperms.
Spermatogonia → Spermatocyte → Spermatid → Sperms. 

Hence, option A is the correct answer.

Note: Spermatogenesis, the source, and advancement of the sperm cells inside the male organ, the testicles. The testicles are made out of various meager firmly wound tubules known as the seminiferous tubules, the sperm cells are delivered inside the dividers of the tubules. Inside the dividers of the tubules, additionally, are numerous haphazardly dissipated cells, called sertoli cells, that capacity to help and support the juvenile sperm cells by giving them supplements and blood items. As the youthful germ cells develop, the sertoli cells help to move them from the external surface of the seminiferous tubule to the focal channel of the tubule.
