During spermatogenesis, the transformation of a round spermatid into a mature spermatozoon, involving acrosome formation, tail development and cytoplasmic condensation, is termed:
- A Spermatocytogenesis
- B Spermiogenesis ✓
- C Meiosis II
- D Spermiation
Correct answer: B. Spermiogenesis
Explanation
Spermiogenesis is the morphological remodelling of a round haploid spermatid into a spermatozoon, involving acrosome formation from the Golgi apparatus, flagellum development, nuclear condensation and shedding of excess cytoplasm as the residual body. No cell division occurs during this step. Spermiation is the separate process of release of the matured spermatozoon from the Sertoli cell into the tubular lumen.
