Question

Identify the set of correct statement:
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

• A. C, D and E only
• B. A, B, C and D only
• C. A, C, D and E only
• D. B, C, D and E only

Answer 1

The Correct Option is D

The problem asks which statements about different flowering plants are correct. Let's analyze each statement:

• A. The flowers of Vallisneria are colourful and produce nectar.
  Vallisneria is a submerged aquatic plant whose flowers are generally pale and do not produce nectar, as they do not rely on insect pollination. Hence, statement A is incorrect.
• B. The flowers of waterlily are not pollinated by water.
  Water lilies are primarily pollinated by insects and not water. Hence, statement B is correct.
• C. In most water-pollinated species, the pollen grains are protected from wetting.
  Water-pollinated species tend to have adaptations to prevent pollen grains from getting wet, such as hydrophobic surfaces. This statement is correct.
• D. Pollen grains of some hydrophytes are long and ribbon-like.
  This is an adaptation to efficiently travel through water and reach the female flower. This statement is correct.
• E. In some hydrophytes, the pollen grains are carried passively inside water.
  Some hydrophytic plants release pollen into the water to passively reach other plants. This statement is correct.

Based on this analysis, the correct set of statements is B, C, D, and E, matching the option: B, C, D and E only.
