Question

Hydrophily constitutes a major mode of pollination in most of the aquatic angiospermous plants. Almost all the aquatic dicot and monocot plants require water for the transport of male gametes and for fertilisation.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

The Correct Option is D

Hydrophily is the mode of pollination (transfer of pollen grains from the mature anther of a flower to the stigma of another flower) which is accomplished through the agency of water. Pollination by water is quite rare in flowering plants and is limited to only about 30 genera, mostly monocotyledons e.g., Vallisneria, Zostera, Ceratophyllum, etc. In many aquatic plants with emergent flowers, pollination occurs by wind or insects, e.g., lotus, water lily, water hyacinth, etc.
