Answer: (D) In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.. Answer: (D) In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.

  1. A.In spermiogenesis spermatozoa from sertoli cells are released into the cavity of seminiferous tubules, while in spermiation spermatozoa are formed.
  2. B.In spermiogenesis spermatozoa are formed, while in spermiation spermatids are formed.
  3. C.In spermiogenesis spermatids are formed, while in spermiation spermatozoa are formed.
  4. D.In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.✓

Correct Answer

(D) In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.

Solution & Explanation

Answer: (D) In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules. Solution: NCERT defines spermiogenesis as the transformation of spermatids into spermatozoa (sperms), and spermiation as the release of sperms, whose heads were embedded in Sertoli cells, from the seminiferous tubules. Option D correctly states sperms are formed in spermiogenesis and released in spermiation. NCERT Reference: Ch 2, p.31, line 36 — "The spermatids are transformed into"
