Question

Given below are a few statements with respect to spermatogenesis in a human male.
(i) Sperms are released from the seminiferous tubules by the process of spermiation.
(ii) Spermiogenesis involves the maturation of spermatids into sperms.
(iii) Spermatogonia produce spermatids by the process of spermiogenesis.
(iv) Meiosis II in secondary spermatocytes results in the formation of four equal haploid spermatids.
(v) Primary spermatocyte completes the first meiotic division forming two equal, diploid cells called secondary spermatocytes.
Choose the option with all true statements from the given options:

• A. (i), (ii) and (iv)
• B. (ii), (iii) and (v)
• C. (ii), (iv) and (v)
• D. (i), (ii) and (iv)

Hint:

Remember: Spermatogonia → Primary spermatocytes → Secondary spermatocytes → Spermatids → Sperm.

Answer 1

The Correct Option is A

(i) is correct — spermiation is the release of sperm from Sertoli cells.
(ii) is correct — spermiogenesis is the transformation of spermatids into mature sperm.
(iv) is correct — secondary spermatocytes undergo meiosis II to form haploid spermatids.
(iii) is incorrect — spermatogonia divide mitotically to produce primary spermatocytes, not directly spermatids.
(v) is incorrect — primary spermatocytes undergo meiosis I to form secondary spermatocytes, which are haploid, not diploid.
