NEET (UG) 2025 — Question 95

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R)

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.

In light of the above statements, choose the most appropriate answer from the options given below.

Option A:
Both A and R are true and R is the correct explanation of A.
Option B:
Both A and R are true and R is NOT the correct explanation of A.
Correct
Option C:
A is true but R is false.
Option D:
A is false but R is true.

Answer: B

Step-by-step solution

Assertion (A) is true: wind- and water-pollinated flowers are generally not colourful and do not produce nectar, as they rely on abiotic agents. Reason (R) is also true: such flowers produce enormous amounts of pollen grains to compensate for the random, non-targeted transfer by wind or water. However, the reason does not explain the assertion; the lack of colour and nectar is an adaptation to abiotic pollination, not a direct consequence of high pollen production. Therefore, both A and R are true, but R is not the correct explanation of A. Hence, the correct option is B.
