Biology Question 102 – NEET-UG 2025

← Back
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 the light of the above statements, choose the correct answer from the options given below :

Recall the characteristics and adaptations of flowers pollinated by abiotic agents like wind (anemophily) and water (hydrophily).

Step 1: Evaluate Assertion (A)✦ Active

Assertion (A) states that wind and water pollinated flowers are not very colourful and do not produce nectar. This is true because these flowers do not rely on animal pollinators, which are attracted by such features. Instead, they rely on abiotic agents (wind or water) for pollen dispersal.

Step 2: Evaluate Reason (R)○ Expand

Reason (R) states that these flowers produce enormous amounts of pollen grains. This is also true. Since pollination by wind and water is a chance event, producing a large quantity of pollen increases the probability of pollen reaching the stigma of another flower, compensating for the inefficiency of abiotic dispersal.

Step 3: Determine the Relationship between A and R○ Expand

Both Assertion (A) and Reason (R) are true statements describing adaptations of wind and water pollinated flowers. However, the reason why these flowers are not colourful or nectar-producing (A) is because they do not need to attract animal pollinators. The production of enormous pollen grains (R) is an adaptation to overcome the random nature and inefficiency of abiotic pollination. Therefore, R is not the correct explanation for A, even though both statements are individually correct.

💡 Teacher's Secret Hint

Distinguish between a true statement and a correct explanation. Two true statements may not always have a cause-and-effect relationship where one explains the other.
