Solution

Pollination in Vallisneria :

  1. In Vallisneria, water is the pollinating agent.
  2. So, the pollen grains are wrapped by mucilaginous coating to protect them from getting wet by water.
  3. The pollen grains from the male flowers are dispersed into the surface of the water.
  4. The flowers of female Vallisneria come on the water surface through the long stalk to collect the pollens.
