| List-I Terms | List-II Features |
|---|---|
| (A) Spermatogenesis | (I) Nutrition to germ cells |
| (B) Acrosome | (II) Testicular hormones |
| (C) Leydig's cells | (III) Penetration of sperm |
| (D) Sertoli cells | (IV) Formation of sperms |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
(A) Spermatogenesis — this matches (IV) Formation of sperms. Spermatogenesis is the process by which the testis produces sperms. Spermatogonia in the seminiferous tubules form spermatocytes, then spermatids, which change into sperms.
(B) Acrosome — this matches (III) Penetration of sperm. The acrosome is the cap-like structure on the head of the sperm. Its enzymes help the sperm enter the ovum at fertilisation.
(C) Leydig’s cells — this matches (II) Testicular hormones. These interstitial cells lie between the seminiferous tubules. They synthesise and secrete androgens, the testicular hormones.
(D) Sertoli cells — this matches (I) Nutrition to germ cells. Sertoli cells line the seminiferous tubules along with the germ cells. They provide nutrition to the germ cells as these develop into sperms.
