2. The flowers of waterlily are not pollinated by water.
3. In most of water-pollinated species, the pollen grains are protected from wetting.
4. Pollen grains of some hydrophytes are long and ribbon like.
5. In some hydrophytes, the pollen grains are carried passively inside water.

• B, C, D and E only

• C, D and E only

• A, B, C and D only

Answer 1

B, C, D and E only

Explanation:

• Vallisneria flowers are colourless and do not yield nectar.
• Insects or the wind pollinate the water lily flowers, which appear above the water’s surface.
• The mucilage layer in the majority of water-pollinated plants shields the pollen grains from moisture.
• Certain hydrophytes have long, ribbon-like pollen grains. This is accurate since some hydrophytes have longer pollen grains that make it easier for them to spread throughout water.
• Pollen grains are passively transported across water in certain hydrophytes, such as Vallisneria.
