Match the following structures/cells of the male reproductive system with their correct functions/characteristics: Column I (Structure/Cell) A. Seminiferous tubules B. Sertoli cells C. Leydig cells D. Epididymis E. Vas deferens Column II (Function/Characteristic) I. Site of sperm production II. Synthesis and secretion of androgens III. Storage and transport of sperms IV. Provide nutrition to germ cells V. Part of female accessory ducts

Correct answer: B A-I, B-IV, C-II, D-III, E-III

Let's correctly match the structures/cells with their functions/characteristics based on NCERT: A. Seminiferous tubules: These are highly coiled tubules in which sperms are produced. So, A matches with I. B. Sertoli cells: These cells are present inside the seminiferous tubules and provide nutrition to the germ cells. So, B matches with IV. C. Leydig cells (Interstitial cells): These cells are located in the interstitial spaces outside the seminiferous tubules and synthesise and secrete testicular hormones called androgens. So, C matches with II. D. Epididymis: The epididymis is part of the male sex accessory ducts that store and transport sperms. So, D matches with III. E. Vas deferens: The vas deferens is also part of the male sex accessory ducts that store and transport sperms. So, E matches with III. (Note: Option B has 'E-III' which correctly reflects its role in transport, similar to epididymis. Option A has 'E-V' which is incorrect as vas deferens is not part of female accessory ducts). Female accessory ducts are oviducts, uterus, vagina. Therefore, the correct match is A-I, B-IV, C-II, D-III, E-III.
