Vallisneria

Vedclass · Answer

(B) In $Vallisneria$,the female flower reaches the surface of the water by a long stalk,and the male flowers or pollen grains are released on to the surface of the water. They are carried passively by water currents to reach the female flowers. This is a classic example of epihydrophily (pollination at the water surface). In contrast,$Hydrilla$ and sea grasses are also pollinated by water,but $Vallisneria$ is the specific example cited in $NCERT$ for pollination at the water surface.
