Answer 1

The Correct Option is D

Concept:
Flowering plants show different types of pollination adaptations. Some plants are pollinated by water, some by insects, some by wind and some by animals.

Step 1: Check statement (A).
Some aquatic plants show long ribbon-like pollen grains. This helps pollen move in water. So, statement (A) is correct.

Step 2: Check statement (B).
In some cases, flowers provide a safe place for insects to lay eggs. This acts as a floral reward. So, statement (B) is correct.

Step 3: Check statement (C).
Insect robbers take pollen or nectar but do not help in pollination. So, statement (C) is also correct.

Step 4: Check statement (D).
Most flowering plants produce bisexual flowers, not homosexual or unisexual flowers. Therefore, statement (D) is incorrect.

Step 5: Final conclusion.
The incorrect statement is: \[ \boxed{\text{(D)}} \]
