Assertion (A): Both wind and water pollinated flowers are not very colourful and do not produce nectar.
Reason (R): The flowers produce enormous amount of pollen grains in wind and water pollinated flowers.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is NOT the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Explanation
Both statements are true facts of abiotic pollination, but Reason does not explain why they lack colour/nectar (lack of biotic pollinators is the cause).
Detailed Solution
Wind and water pollinated flowers do not need visual cues or rewards like nectar because their vectors are abiotic, making Assertion true. They produce copious pollen to compensate for random passive dispersal loss, making Reason true. However, R is not the explanation for A.
