Select the statements that are true for pollination mechanism in flowering plants from the given options:
Show Hint
Water pollination is uncommon and involves adaptations like mucilage-covered pollen grains.
Updated On: Jan 13, 2026
- In Vallisneria, the female flowers are pollinated by pollen grains inside the water.
- In Zostera, pollen grains are released on the surface of water.
- In most of the water-pollinated species, pollen grains are covered by a mucilaginous coating.
Pollination by water is quite rare and limited to about 30 genera.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
(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.
(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.
