Question

Long ribbon-like pollen grains are seen in some:

• A. Aquatic plants
• B. Wind-pollinated grasses
• C. Gymnosperms
• D. Bird-pollinated flowers

Hint:

Hydrophily occurs in very few plants. Remember examples like Zostera} and Vallisneria} that show adaptations like ribbon-like pollen.

Answer 1

The Correct Option is A

Step 1: Some aquatic plants undergo pollination through water, a process known as hydrophily.
Step 2: In such plants, pollen grains are modified for floating and travel.
Step 3: Zostera}, an aquatic plant, produces long, ribbon-like pollen grains which help in floating in water and reaching the stigma.
Step 4: This structure is not found in wind or bird-pollinated flowers or gymnosperms.
\[ \Rightarrow \text{Therefore, the correct answer is } \boxed{\text{(A) Aquatic plants}}. \]
