The immature male germ cells undergo division to produce sperms by the process of spermatogenesis. Choose the correct one with reference to above.

Options

A. Spermatogonia have 46 chromosomes and always undergo meiotic cell division.
B. Primary spermatocytes divide by mitotic cell division.
C. Secondary spermatocytes have 23 chromosomes and undergo second meiotic division.
D. Spermatozoa are transformed into spermatids.

Answer

C

Explanation

Spermatogonia are diploid cells on the inside wall of seminiferous tubules that multiply by mitotic edivisions, some of the spermatogonia called primary spermatocyte undergo meiosis-I to give rise to secodnary spermatocytes (haploid). Each secondary spermatocyte undergoes meiosis-II to give rise to two haploid spermatids which are transferred to spermatozoa by speriogenesis.
