Question:medium

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

Show Hint

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

  • (C), (A), (D), (E), (B)
  • (A), (D), (E), (C), (B)
  • (C), (A), (D), (B), (E)
Show Solution

The Correct Option is B

Solution and Explanation

Stage 1: Origin - Spermatogonia.
Spermatogenesis initiates with spermatogonia, diploid stem cells found in the seminiferous tubules.
Stage 2: Production of Primary Spermatocytes.
Spermatogonia divide via mitosis, yielding primary spermatocytes, which remain diploid.
Stage 3: Production of Secondary Spermatocytes.
Primary spermatocytes undergo meiosis I, resulting in haploid secondary spermatocytes.
Stage 4: Production of Spermatids.
Secondary spermatocytes complete meiosis II, producing haploid spermatids.
Stage 5: Production of Spermatozoa.
Spermatids mature through spermiogenesis, differentiating into motile spermatozoa.
Stage 6: Summary.
The correct progression is: Spermatogonium → Primary spermatocyte → Secondary spermatocyte → Spermatids → Spermatozoa.
