Well exposed stamens, large feathery stigma, single ovule in each ovary and numerous flowers packed into inflorescence is characteristic feature of

Options

A. Entomophily
B. Anemophily
C. Ornithophily
D. Zoophily

Answer

To solve the question regarding the characteristic features of certain flowers, we can break down the information as follows:

### Step-by-Step Solution:

1. **Identify Key Features**: The question lists specific features of the flowers: well-exposed stamens, large feathery stigma, single ovule in each ovary, and numerous flowers packed into an inflorescence.

2. **Understand Pollination Types**: We need to understand the different types of pollination mentioned in the options:
- **Entomophily**: Pollination by insects.
- **Anemophily**: Pollination by wind.
- **Ornithophily**: Pollination by birds.
- **Zoophily**: Pollination by animals.

3. **Analyze Each Option**:
- **Entomophily**: Flowers that are pollinated by insects typically have bright colors, sticky pollen, and enclosed stamens. This does not match our features.
- **Anemophily**: Wind-pollinated flowers often have exposed stamens and feathery stigmas to catch pollen from the air. They usually have a single ovule in each ovary and can be found in dense inflorescences. This matches our features.
- **Ornithophily**: Flowers that attract birds usually have bright colors and specific arrangements to facilitate bird pollination, which does not align with the features given.
- **Zoophily**: Flowers that rely on animals for pollination often have hairy pollen grains to adhere to animals, which does not match the features described.

4. **Conclusion**: Based on the analysis, the correct answer is **Anemophily**, as it aligns perfectly with the characteristics provided in the question.

### Final Answer:
The characteristic feature of well-exposed stamens, large feathery stigma, single ovule in each ovary, and numerous flowers packed into inflorescence is indicative of **Anemophily** (wind pollination).
