Match the type of placentation in Column I with its corresponding structural characteristic and plant example in Column II . Column I Column II (a) Axile (i) False septum formation in a unilocular ovary; Mustard (b) Parietal (ii) Single ovule attached at the ovary base; Sunflower (c) Free central (iii) Multilocular ovary with central attachment; Lemon (d) Basal (iv) Septa are completely absent; Dianthus Select the co
Options
- A(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
- B(a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)
- C(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
- D(a)-(iv), (b)-(ii), (c)-(iii), (d)-(i)
Correct answer
A. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
Step-by-step solution
Refer: NCERT | Class 11 | Page: 65 | Paragraph: 2 Axile placentation occurs in a multilocular ovary where ovules are attached to the central axis. Example: Lemon. Thus, (a) matches (iii). Parietal placentation occurs when ovules develop on the inner wall of the ovary. A false septum may form, making the unilocular ovary bilocular. Example: Mustard. Thus, (b) matches (i). Free central placentation features ovules borne on a central axis with septa completely absent. Example: Dianthus. Thus, (c) matches (iv). Basal p
