Question

Refer to the given characteristics of some flowers.
(i) LIght and non-sticky pollen grains
(ii) Exserted stigmas and anthers
(iii) Large, often feathert stigmas
(iv) Flowers colourless, odourless and nectarless
(v) Common in grasses

Above features are the characteristics of

a)
anemophily
b)
hydrophily
c)
entomophily
d)
zoophily.

Correct answer is option 'A'. Can you explain this answer?

Answer

Anemophily is a mode of cross pollination or transfer of pollen grains from a mature anther to the stigma of a pistil which is accomplished through the agency of wind.
Example: coconut palm, data palm, maize, many grasses, Cannabis, etc.

Answer

Characteristics of Anemophily
Anemophily refers to the process of pollination by wind, which is characterized by specific adaptations in flowering plants. The characteristics listed in the question distinctly point towards this type of pollination.
Key Characteristics:
- Light and Non-Sticky Pollen Grains:
Wind-pollinated plants produce pollen that is lightweight and non-sticky. This ensures that the pollen can be easily carried by the wind over long distances without adhering to surfaces.
- Exserted Stigmas and Anthers:
In anemophilous plants, both stigmas and anthers are often protruded beyond the flower. This positioning maximizes the exposure to the wind, allowing for efficient pollen dispersal and capture.
- Large, Often Feathery Stigmas:
The stigmas of wind-pollinated flowers are typically large and feathery, which increases their surface area. This adaptation enhances the likelihood of capturing airborne pollen.
- Flowers Colourless, Odourless, and Nectarless:
Anemophilous flowers do not need to attract pollinators with colors, scents, or nectar, as they rely solely on the wind for pollen transfer. Their flowers are usually inconspicuous.
- Common in Grasses:
Many grasses are anemophilous, as they exhibit these characteristics. They thrive in open environments where wind can effectively facilitate pollination.
Conclusion:
The features listed in the question align perfectly with the characteristics of anemophily, making option 'A' the correct answer. The adaptations of these plants favor wind as the primary means of pollination, distinguishing them from other pollination strategies like hydrophily, entomophily, and zoophily.
