Arrange the given structures formed during spermatogenesis in correct…

The correct answer is Option (1) → (D), (B), (C), (A)

(D) Spermatogonia — first. These diploid cells on the wall of the seminiferous tubules multiply by mitosis; some become primary spermatocytes.

(B) Secondary spermatocytes — second. The first meiotic division of a primary spermatocyte gives two haploid secondary spermatocytes.

(C) Spermatids — third. The second meiotic division gives four haploid spermatids.

(A) Spermatozoa — last. Spermatids change into sperms by spermiogenesis.

NCERT Extract:
Gametogenesis – “… In testis, the immature male germ cells (spermatogonia) produce sperms by spermatogenesis that begins at puberty. The spermatogonia (sing. spermatogonium) present on the inside wall of seminiferous tubules multiply by mitotic division and increase in numbers. Each spermatogonium is diploid and contains 46 chromosomes. Some of the spermatogonia called primary spermatocytes periodically undergo meiosis. 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). … The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis.”
