Match List I (Placentation) with List II (Example): List I (Placentation): A. Marginal; B. Axile; C. Parietal; D. Basal List II (Example): I. Mustard; II. Pea; III. Marigold; IV. Lemon Choose the correct answer from the options given below: (NEET 2026)
Answer: (A) A-II, B-IV, C-I, D-III. Marginal placentation (placenta along the ventral suture, two rows of ovules) occurs in Pea; axile placentation (ovules on a central axis of a multilocular ovary) occurs in lemon; parietal placentation (ovules on the inner wall of a one-chambered ovary with a false septum) occurs in mustard; and basal placentation (a single ovule at the ovary base) occurs in marigold.
- A.A-II, B-IV, C-I, D-III✓
- B.A-I, B-III, C-II, D-IV
- C.A-III, B-I, C-IV, D-II
- D.A-IV, B-II, C-I, D-III
Correct Answer
(A) A-II, B-IV, C-I, D-III
Solution & Explanation
Marginal placentation (placenta along the ventral suture, two rows of ovules) occurs in Pea; axile placentation (ovules on a central axis of a multilocular ovary) occurs in lemon; parietal placentation (ovules on the inner wall of a one-chambered ovary with a false septum) occurs in mustard; and basal placentation (a single ovule at the ovary base) occurs in marigold. So A-II, B-IV, C-I, D-III, which is option (1) = A. NCERT Reference: Ch 5, p.65, line(s) 27-39 — "In marginal placentation the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge forming two rows, as in pea"
