Question

Arrange the following steps of Spermatogenesis in correct sequence:
(A) Primary spermatocyte
(B) Spermatozoa
(C) Spermatogonium
(D) Secondary spermatocyte
(E) Spermatids

• A. (E), (C), (A), (D), (B)
• B. (C), (A), (D), (E), (B)
• C. (A), (D), (E), (C), (B)
• D. (C), (A), (D), (B), (E)
• E.

Hint:

Mnemonic: "Good Students Are Smart" = Gonium → Spermatocyte (Primary) → Spermatocyte (Secondary) → Spermatid → Spermatozoa.

Answer 1

The Correct Option is B

Step 1: Starting point - Spermatogonia.
Spermatogenesis begins with spermatogonia, which are diploid stem cells located in the seminiferous tubules.
Step 2: Formation of primary spermatocytes.
Spermatogonia undergo mitosis to form primary spermatocytes, which are still diploid.
Step 3: Formation of secondary spermatocytes.
Primary spermatocytes undergo meiosis I to form secondary spermatocytes, which are haploid.
Step 4: Formation of spermatids.
Secondary spermatocytes undergo meiosis II to produce spermatids, which are also haploid.
Step 5: Formation of spermatozoa.
Spermatids undergo a maturation process called spermiogenesis, where they transform into motile spermatozoa.
Step 6: Conclusion.
Thus, the correct sequence is (C) Spermatogonium → (A) Primary spermatocyte → (D) Secondary spermatocyte → (E) Spermatids → (B) Spermatozoa.
