Question

Describe how pollination occurs in Vallisneria?​

Answer 1

Vallisneria is well-adapted for cross-pollination. It is a dioecious plant where male and female plants are separate. Pollination occurs with the help of water and such flowers are called hydrophilons. The male flowers are very small and on maturity, get detached. They float on the surface of water. The female plants bear female flowers that remains afloat on long stalks. Free floating male flowers pollinate the female flowers on surface of water. ​
