Answer: (D) FSH, Leydig cells, Sertoli cells, spermatogenesis. Answer: (D) FSH, Leydig cells, Sertoli cells, spermatogenesis Solution: This figure-based question maps labelled positions in the hormonal-regulation flowchart of spermatogenesis.
- A.ICSH, Interstitial cells, Leydig cells, spermatogenesis
- B.FSH, Sertoli cells, Leydig cells, spermatogenesis
- C.ICSH, Leydig cells, Sertoli cells, spermatogenesis
- D.FSH, Leydig cells, Sertoli cells, spermatogenesis✓
Correct Answer
(D) FSH, Leydig cells, Sertoli cells, spermatogenesis
Solution & Explanation
Answer: (D) FSH, Leydig cells, Sertoli cells, spermatogenesis Solution: This figure-based question maps labelled positions in the hormonal-regulation flowchart of spermatogenesis. Per NCERT, FSH acts on the Sertoli cells while LH acts on the Leydig cells which secrete androgens that stimulate spermatogenesis; matching the labels gives FSH (A), Leydig cells (B), Sertoli cells (C) and spermatogenesis (D). Option D correctly lists these terms; the other options misplace ICSH/Sertoli/Leydig. NCERT Reference: Ch 2, p.31, line 49 — "secretion of androgens. Androgens, in turn, stimulate the process of"
