Which among the following statements are correct :

(A) Insect  pollinated flowers often have a single  ovule in each ovary and numerous flowers packed into an inflorescence.

(B) Pollination by water is quite rare in flowering plants and is limited to about 30 genera, mostly dicotyledons.

(C)  Vallisneria and Hydrilla are  water pollinated plants but  Zostera are wind pollinated flower .

(D) In a majority of aquatic plants such as water hyacinth and water lily, the flowers emerge above the level of water and are pollinated by insects or wind.

(E) To sustain animal visits, the flowers have to provide rewards to the animals.

Choose the correct answer from the given options.

D and E  only.

The correct answer is Option (3) – D and E  only.

Wind pollination is a common form of abiotic pollination.It requires light and non-sticky pollen grains that can be carried by wind currents. Wind pollinated flowers often have a single ovule in each ovary and numerous flowers packed into an inflorescence.

Water pollination is rare in flowering plants and is primarily observed in about 30 genera, mostly monocotyledons. Lower plant groups such as algae, bryophytes, and pteridophytes rely on water for the transport of male gametes. Examples of water-pollinated plants include Vallisneria, Hydrilla, and marine seagrasses like Zostera.

Not all aquatic plants use water for pollination; many, such as water hyacinths and water lily, are pollinated by insects or wind.

To sustain animal visits, the flowers have to provide rewards to the animals . Nectar and pollen grains are the usual floral rewards. For harvesting the reward (s) from the flower the animal visitor comes in contact with the anthers and the stigma.
