Question

Comment upon the mode of pollination in Vallisneria.

Answer 1

Vallisneria (Water nymph):

1. Vallisneria is a submerged aquatic plant.
2. It exhibits hydrophily, i.e., pollination by water.
3. Male flowers float on the water’s surface after they are removed from the parent plant.
4. Female blooms have a lengthy stem that carries them to the water’s surface.
5. Pollination occurs when male flowers floating on water come into contact with female flowers on the surface, transferring pollen.
