Question

Differentiate between sertoli cells and spermatogonial cells.

Answer 1

Sr. No.	Feature	Sertoli cells	Spermatogonial cells
1.	Nature	These are supporting cells attached to the basement membrane and are not germ cells.	These are primary germ cells produced by the basement membrane of seminiferous tubules.
2.	Function	They provide mechanical support, protection, and nutrition to developing germ cells.	They produce spermatozoa by undergoing continuous cell division and differentiation.
3.	Role in spermatogenesis	They act as nurse cells that facilitate the maturation of developing sperm.	They act as the precursor cells that divide to eventually form mature sperm.
