Question 110: Match List – I with List – II :
| List – I | List – II |
|---|---|
| (a) Imbricate | (i) Calotropis |
| (b) Valvate | (ii) Cassia |
| (c) Vexillary | (iii) Cotton |
| (d) Twisted | (iv) Bean |
Choose the correct answer from the options given below :
(1) (a) – (ii), (b) – (i), (c) – (iii), (d) – (iv)
(2) (a) – (ii), (b) – (i), (c) – (iv), (d) – (iii)
(3) (a) – (ii), (b) – (iv), (c) – (iii), (d) – (i)
(4) (a) – (i), (b) – (iii), (c) – (iv), (d) – (ii)
Answer: Option (2)
Explanation:
Imbricate aestivation is a type of arrangement in which the margins of sepals or petals overlap each other but not in any definite direction.
This type of aestivation is seen in Cassia, where petals show irregular overlapping.
Valvate aestivation is the arrangement in which sepals or petals touch each other at the margins without overlapping.
This type is commonly observed in Calotropis.
Vexillary aestivation is a characteristic feature of flowers belonging to the family Fabaceae.
In this arrangement, there is one large posterior petal called the standard, two lateral petals called wings, and two anterior petals forming the keel.
This type of aestivation is seen in Bean.
Twisted aestivation is a type in which one margin of each petal overlaps the next petal in a regular manner.
This arrangement is typically found in Cotton.
Therefore, the correct matching is (a) – (ii), (b) – (i), (c) – (iv), and (d) – (iii).
Hence, the correct answer is Option (2).
