why are flowers in Vallisneria small and inconspicuous.
Answers
Answer:
Most aquatic plants have flowers that grow into the air, where they are pollinated by insects. Plants that are water-pollinated usually have small, inconspicuous male flowers that release lots of pollen grains that drift in the water where they are caught by the large, feathery stigmas of female flowers. Some species growing in shallow pools have long, noodle-like pollen that sticks to female flowers. Many varieties of seaweed are water-pollinated; some invasive water-pollinated plants can choke ponds and slow-moving streams.

Answer:
The pollination in the Vallisneria is achieved with the help of water. In Vallisneria, the female flowers are submerged in the water. They reach the surface of water by the long stalk on reaching maturity. At this time, the male flowers are released onto the surface of water. With the help of the water, the pollens come in contact with the female flowers and the pollination is achieved.
In the case of water lily, the female flowers remain submerged in water. The pollen grains are released inside the water. The pollen grains are long, thread-like and are carried with the water and reach the stigma and achieve pollination.
