Arrange the given structures which are involved in spermatogenesis in…

The correct answer is Option (3) → (C), (A), (B), (D)

(C) Primary spermatocyte — first. Some spermatogonia in the seminiferous tubules grow into primary spermatocytes. These are diploid cells with 46 chromosomes, and they undergo meiosis.

(A) Secondary spermatocyte — second. The first meiotic division (reduction division) of one primary spermatocyte gives two equal haploid secondary spermatocytes with 23 chromosomes each.

(B) Spermatids — third. The second meiotic division of the secondary spermatocytes gives four equal haploid spermatids in all.

(D) Spermatozoa — last. The spermatids change shape and become spermatozoa (sperms). This change is called spermiogenesis.

Note: A similar question was also asked in CUET (UG) 2026 on 06-06-2026 (Slot 1), on 15-05-2026 (Slot 1) and on 14-05-2026 (Slot 1), and in CUET (UG) 2025 on 20-05-2025 (Slot 1).

NCERT Extract:
Gametogenesis – “… A primary spermatocyte completes the first meiotic division (reduction division) leading to formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes each. The secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids (Figure 2.5).”
Gametogenesis – “… The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis.”
