Given below are two statements: Statement I: The release of sperms...
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:
Options
- ABoth statement I and statement II are incorrect
- BStatement I is correct but statement II is incorrect
- CStatement I is incorrect but statement II is correct
- DBoth statement I and statement II are correct
Correct answer
D. Both statement I and statement II are correct
Step-by-step solution
Statement I:
- Seminiferous tubules are the site of sperm production in testes.
- Spermiation is the process of release of mature spermatozoa from the seminiferous tubules into the lumen of the tubules.
- The released spermatozoa are transported through the rete testis, epididymis, and vas deferens to reach the urethra for ejaculation during sexual intercourse.
Statement II:
- Spermatogonia are the diploid cells that undergo meiosis to form haploid sperm cells.
- Spermatogenesis is the process of sperm cell production that involves meiosis, spermiogenesis, and spermiation.
- Spermiogenesis is the process of transformation of round spermatids into elongated and motile spermatozoa.
Explanation:
From the above statements, we can conclude that:
- Statement I is correct because spermiation is the process of release of mature spermatozoa from the seminiferous tubules into the lumen of the tubules.
- Statement II is incorrect because spermiogenesis is the process of transformation of round spermatids into elongated and motile spermatozoa, whereas sperm formation from spermatogonia involves meiosis and spermiogenesis.
Therefore, the correct answer is option 'D'.
