Question

Given below are two statements: Statement I: The release of sperms into the seminiferous tubules is called spermiation. Statement II: Spermiogenesis is the process of formation of sperms from spermatogonia.

In the light of the above statements, choose the most appropriate answer from the options given below:

A

Statement I is incorrect but Statement II is correct.

B

Both Statement I and Statement II are correct.

C

Both Statement I and Statement II are incorrect.

D

Statement I is correct but Statement II is incorrect.

Step-by-Step Solution

According to the textbook:

  • Statement I is Correct: After spermiogenesis, sperm heads become embedded in the Sertoli cells and are finally released from the seminiferous tubules (into the lumen) by the process called spermiation .
  • Statement II is Incorrect: Spermatogenesis is the process where immature male germ cells (spermatogonia) produce sperms . Spermiogenesis is specifically the transformation of spermatids into spermatozoa (sperms) .
