Question: 115. Identify the set of correct statements:
A. The flowers of Vallisneria are colourful and produce nectar.
B. The flowers of waterlily are not pollinated by water.
C. In most of water-pollinated species, the pollen grains are protected from wetting.
D. Pollen grains of some hydrophytes are long and ribbon like.
E. In some hydrophytes, the pollen grains are carried passively inside water.
Choose the correct answer from the options given below :
(1) C, D and E only
(2) A, B, C and D only
(3) A, C, D and E only
(4) B, C, D and E only
Answer: Option (4)
Explanation:
Statement A is incorrect because the flowers of Vallisneria are small, inconspicuous, and do not produce nectar, as they are adapted for water pollination.
Statement B is correct because waterlily flowers emerge above the water surface and are pollinated by insects, not by water.
Statement C is correct because in most water-pollinated plants, pollen grains are protected from wetting by a mucilaginous covering.
Statement D is correct as in some hydrophytes like Vallisneria and Zostera, pollen grains are long and ribbon-like to facilitate transport in water.
Statement E is correct because in some hydrophytes, pollen grains are carried passively by water currents to reach the female flowers.
Therefore, the correct set of statements is B, C, D and E.
