Answer 1

The Correct Option is D

- A is incorrect because the flowers of Vallisneria are not colorful and do not produce nectar; they are typically small and unnoticeable.

- B is correct because water lilies are pollinated by insects, not by water.

- C is correct; in water-pollinated species, pollen grains often have special adaptations to prevent wetting, such as being hydrophobic.

- D is correct; some hydrophytes have long, ribbon-like pollen grains that help them to float.

- E is correct; in some hydrophytes, pollen grains are passively carried by the water to fertilize the flowers.
