Question

Refer to the given characteristics of some flowers: I. Flowers are small. They are often packed in inflorescence.
II. Flowers are colourless, nectarless and odourless.
III. Well exposed stamens.
IV. Pollen grains produced in large number, light and non-sticky.
V. Flowers often have a single ovule in each ovary.
VI. Stigma large, often feathery. The above features are the characteristics of

• A. Self-pollination
• B. Anemophily (pollination by wind)
• C. Ornithophily (pollination by birds)
• D. Entomophily (pollination by insects)

Hint:

Anemophilous flowers are small, colourless, nectarless, with exposed stamens and feathery stigma.

Answer 1

The Correct Option is B

Concept:
Anemophily means pollination by wind. Wind-pollinated flowers have special features that help pollen disperse through air and reach the stigma.

Step 1: Check flower size and arrangement.
Wind-pollinated flowers are usually small and not showy. They are often grouped in inflorescences so that pollen release becomes easier.

Step 2: Check colour, nectar and odour.
Wind-pollinated flowers do not need to attract insects or birds. So they are generally: \[ \text{colourless} \] \[ \text{nectarless} \] \[ \text{odourless} \]

Step 3: Check stamens and pollen.
Well-exposed stamens help pollen grains to be released into air. Pollen grains are produced in large numbers because wind pollination is uncertain. They are light and non-sticky so they can be carried easily by wind.

Step 4: Check stigma.
Large and feathery stigma helps trap floating pollen grains from air.

Step 5: Final conclusion.
All the given features are characteristics of wind pollination. Hence: \[ \boxed{\text{(B) Anemophily}} \]
