Question

Pollination occurs in Vallisneria by:

• A. By air
• B. By insects
• C. By water
• D. None of these

Hint:

Think about the habitat of Vallisneria — it is fully aquatic.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Vallisneria is a submerged aquatic (hydrophyte) plant. Aquatic plants that release pollen directly into the water for pollination show hydrophily (water pollination).

Step 2: Applying it to Vallisneria:
In Vallisneria, the male flowers detach from the plant and float on the water surface. The female flowers reach the surface on long stalks. Pollen from the floating male flowers is carried by water currents to the female flowers, where pollination occurs.

Final Answer:
Pollination in Vallisneria occurs by water.
Option (C) is correct.
