Question

Which of the following is a very rare water pollinating plant? Hydrilla Vallisneria Zostera None of the choices​

Answer 1

Answer:

Pollination carried out through water is called hydrophily. Pollination by water is quite rare in flowering plants. (E.g. freshwater plants like Vallisneria, Hydrilla; marine water plants like Zostera). Light unwettable pollen grains are present in these plants.

Answer 2

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.
