Question

Select the statements that are true for pollination mechanism in flowering plants from the given options:

• A. In Vallisneria, the female flowers are pollinated by pollen grains inside the water.
• B. In Zostera, pollen grains are released on the surface of water.
• C. In most of the water-pollinated species, pollen grains are covered by a mucilaginous coating.
• D. Pollination by water is quite rare and limited to about 30 genera.

Hint:

Water pollination is uncommon and involves adaptations like mucilage-covered pollen grains.

Answer 1

The Correct Option is D

(i) True: In Vallisneria, pollination occurs underwater.
(ii) False: In Zostera, pollen grains are also released underwater, not on the surface.
(iii) True: Mucilaginous coating protects pollen in water-pollinated species.
(iv) True: Water pollination is rare and restricted to about 30 genera.
