A) Spermatid, Spermatocyte, Spermatogonia, Spermatozoa
B) Spermatogonia, Spermatocyte, Spermatozoa, Spermatid
C) Spermatogonia, Spermatozoa, Spermatocyte, Spermatid
D) Spermatogonia, Spermatocyte, Spermatid, Spermatozoa
Correct Answer: D
Solution :
[d] The correct sequence of sperm formation is Spermatogonia \[\to \] Spermatocyte \[\to \]Spermatid \[\to \]Spermatozoa. Spermatogonia are present on the inside wall of seminiferous tubule which undergoes mitotic division and increase their number. Primary spermatocytes are some of the Spermatogonia, which periodically undergo meiosis and for secondary spermatocytes. These undergo the second meiotic division to produce four, equal haploid spermatids. The spermatids are further transformed into spermatozoa (sperm) and are finally released.
