Question

Consider the following statements depicting adaptation of flowers to carryout successful pollination.

1. Stigma is long, sticky and unwettable.
2. Sepals, petals or perianth (if present) have waxy coating.
3. Stamens with long filament and versatile anthers.
4. Tubular corolla is seen.
5. Flowers are noctumal.

Which of the above statements clearly depict hydrophily?

Options

• II and V

• II, III and V

• I and II

• I, III and IV

Answer 1

I and II

Explanation:

• Statements I and II demonstrate hydrophily clearly.
• Hydrophily is a type of water-based pollination.
• It is a reasonably common type of pollination in which pollen is dispersed by the movement of water.
• Water-pollinated flowers have lengthy, sticky, and unwettable stigmas, as well as a waxy coating over the sepals, petals, and/or perianth (if present), and are colourless with no aroma or nectar. All of these adaptations contribute to the success of hydrophily.
