Match List-I with List-II.
| List-I | List-II |
| (A) Acrosome | (I) Female external genitalia |
| (B) Endometrium | (II) Uterus |
| (C) Polar body | (III) Oogenesis |
| (D) Clitoris | (IV) Sperm head |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-IV, B-II, C-III, D-I
Each item in List-I is a part found in a particular structure or formed in a particular process, so each is matched with where it belongs.
(A) Acrosome — this matches (IV) Sperm head. The acrosome is a cap-like structure that covers the front part of the nucleus in the head of the sperm.
(B) Endometrium — this matches (II) Uterus. It is the inner glandular layer of the uterine wall that lines the uterine cavity and changes during each menstrual cycle.
(C) Polar body — this matches (III) Oogenesis. Both meiotic divisions of oogenesis are unequal; the tiny cells formed with the large oocyte or ovum are the polar bodies.
(D) Clitoris — this matches (I) Female external genitalia. It is a tiny finger-like structure at the upper junction of the two labia minora.
NCERT Extract:
Gametogenesis – “… A plasma membrane envelops the whole body of sperm. The sperm head contains an elongated haploid nucleus, the anterior portion of which is covered by a cap-like structure, acrosome.”
The Female Reproductive System – “… The wall of the uterus has three layers of tissue. The external thin membranous perimetrium, middle thick layer of smooth muscle, myometrium and inner glandular layer called endometrium that lines the uterine cavity.”
Gametogenesis – “… It is important to draw your attention that it is at this stage that the primary oocyte within the tertiary follicle grows in size and completes its first meiotic division. It is an unequal division resulting in the formation of a large haploid secondary oocyte and a tiny first polar body (Figure 2.8b).”
The Female Reproductive System – “… The female external genitalia include mons pubis, labia majora, labia minora, hymen and clitoris (Figure 2.3a).”
