Question

In sea grass, pollens are long, ribbon like and without exine exhibiting ________ pollination.

• A. ornithophilous
• B. hypohydrophilous
• C. epihydrophilous
• D. anaemophilous

Hint:

Hydrophily types: Surface $\rightarrow$ Epihydrophily
Underwater $\rightarrow$ Hypohydrophily

Answer 1

The Correct Option is B

Concept: Hydrophily is pollination by water and is of two types:
• Epihydrophily: Pollination occurs on water surface
• Hypohydrophily: Pollination occurs under water

Step 1: Understand sea grass pollination.
Sea grasses are submerged plants; pollination occurs under water.

Step 2: Adaptations.
• Long, ribbon-like pollen
• Lack of exine (outer wall)

Step 3: Identify type.
These features are characteristic of hypohydrophily.

Step 4: Analyze options.
• (A) Ornithophilous: Bird pollination
• (B) Hypohydrophilous: Underwater (correct)
• (C) Epihydrophilous: Surface pollination
• (D) Anemophilous: Wind pollination

Step 5: Conclusion.
Thus, sea grasses show hypohydrophilous pollination. Final Answer: Option (B)
