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 plants, we can break down the information provided step by step.

### Step-by-Step Solution:

1. **Identify the Features**: The question mentions the following features:
- Well-exposed stamens
- Large feathery stigma
- Single ovule in each ovary
- Numerous flowers packed into inflorescence

2. **Understand Pollination Types**: The options given are:
- Entomophilia (pollination by insects)
- Anemophilia (pollination by wind)
- Orthinophilia (pollination by birds)
- Zoophilia (pollination by animals)

3. **Analyze Each Feature**:
- **Well-exposed stamens**: This feature is typical of plants that rely on wind for pollination, as they need to release pollen into the air.
- **Large feathery stigma**: This characteristic helps in capturing airborne pollen grains, which is also indicative of wind-pollinated plants.
- **Single ovule in each ovary**: This is common in plants that are adapted to wind pollination, as it reduces the need for multiple fertilization events.
- **Numerous flowers packed into inflorescence**: This arrangement can increase the chances of pollen being carried by the wind to the stigma of different flowers.

4. **Determine the Correct Option**: Given the characteristics described, the features align with **Anemophilia**, which is the process of wind pollination. The other options do not fit the described characteristics:
- Entomophilia would require sticky pollen and less exposed stamens.
- Orthinophilia would involve adaptations for bird pollination, which is different.
- Zoophilia involves animal pollination, which also does not match the features given.

5. **Conclusion**: Therefore, the correct answer is **Anemophilia**.
