What is the process of transformation of spermatids into spermatozoa called?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Spermiogenesis
Sperm formation in the testis goes in steps. Spermatogonia form primary and then secondary spermatocytes, and the second meiotic division gives round spermatids. A spermatid cannot swim. Its change into a sperm (spermatozoon) is called spermiogenesis. It differs from spermiation, which is the release of finished sperms from the seminiferous tubules, and from spermatogenesis, the whole process from spermatogonia to sperms.
NCERT Extract:
Gametogenesis – “… The secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids (Figure 2.5). … The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis. After spermiogenesis, sperm heads become embedded in the Sertoli cells, and are finally released from the seminiferous tubules by the process called spermiation.”
