Question

what is spermatogonia and what's work??

Answer 1

Spermatogonia-
A spermatogonium (plural: spermatogonia) is an undifferentiated male germ cell. Spermatogonia undergo spermatogenesis to form mature spermatozoa in the seminiferous tubules of the testis.

There are three subtypes of spermatogonia in humans:

1)Type A (dark) cells, with dark nuclei.
These cells are reserve spermatogonial stem cells which do not usually undergo active mitosis.

2)Type A (pale) cells, with pale nuclei.
These are the spermatogonial stem cells that undergo active mitosis. These cells divide to produce Type B cells.

3)Type B cells, which divide to give rise to primary spermatocytes.

Answer 2

Spermatozoa are the mature male gametes in many sexually reproducing organisms. Thus, spermatogenesis is the male version of gametogenesis, of which the female equivalent is oogenesis. In mammals it occurs in the seminiferous tubules of the male testes in a stepwise fashion. Spermatogenesis is highly dependent upon optimal conditions for the process to occur correctly, and is essential for sexual reproduction. DNA methylation and histone modification have been implicated in the regulation of this process.[3] It starts at puberty and usually continues uninterrupted until death, although a slight decrease can be discerned in the quantity of produced sperm with increase in age (see Male infertility).
