Pollination in water hyacinth and water lily is brought about by the agency of -
- water
- insects or wind
- birds
- bats
The Correct Option is B
Solution and Explanation
Correct Answer:
Insects or wind
Explanation:
Though water hyacinth and water lily are aquatic plants, pollination is not usually carried out by water (hydrophily) in these species. Instead:
- Water lily has large, attractive flowers which are often pollinated by insects such as beetles.
- Water hyacinth also relies on insects or wind for pollination, as its flowers emerge above the surface of the water.
Therefore, insects or wind are the primary pollinating agents in these plants, not water.

- CUET (UG) - 2025
- Agriculture
- Double Fertilisation
- Assertion: Insects are important pollinators for many flowering plants. Reasoning: Insects visit flowers to obtain nectar or pollen, and in the process, they inadvertently transfer pollen from one flower to another, facilitating cross-pollination.

Concepts Used:
Pollination and Double Fertilization
Pollination is defined as the pre-fertilization event or process, where pollen grains from another are transferred to the stigma of a flower.
Double fertilization is a complex process that involves the fusion of one female gametophyte with two male gametes.
Types of Pollination:
All plants having flowers completely rely on the pollination method for reproduction. There are 2 types of pollination –
- Self Pollination
- Cross-Pollination
The end products of double fertilization are:
- Diploid Zygote
- Primary Endosperm Nucleus
