Question: 132. Match List I with List II
| List I | List II |
|---|---|
| A. Rose | I. Twisted aestivation |
| B. Pea | II. Perigynous flower |
| C. Cotton | III. Drupe |
| D. Mango | IV. Marginal placentation |
Choose the correct answer from the options given below:
(1) A-II, B-IV, C-I, D-III
(2) A-I, B-II, C-III, D-IV
(3) A-IV, B-III, C-II, D-I
(4) A-II, B-III, C-IV, D-I
Answer: Option (1)
Explanation:
Rose is a classic example of a perigynous flower, where the ovary is semi-inferior and other floral parts are borne on the rim of the thalamus, so A is matched with II.
Pea shows marginal placentation, in which ovules are borne along the margin of a single carpel,
hence B is matched with IV.
Cotton flowers exhibit twisted aestivation, where petals overlap each other in a regular manner,
so C is matched with I.
Mango produces a drupe type of fruit, characterized by a fleshy mesocarp and a hard endocarp enclosing the seed, therefore D is matched with III.
Thus, the correct matching is A-II, B-IV, C-I, D-III.
