Feathery stigma occurs in

Options

A. pea
B. wheat
C. Datura
D. Caesalpinia

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept of Feathery Stigma**:
- Feathery stigma is a characteristic feature of certain plants that aids in wind pollination. The feathery structure increases the surface area, allowing for better capture of pollen grains carried by the wind.

2. **Identifying Pollination Mechanism**:
- Plants with feathery stigmas typically rely on wind for pollination. This means they have adaptations that facilitate the transfer of pollen through air currents.

3. **Characteristics of Wind-Pollinated Plants**:
- Such plants usually exhibit several traits:
- **Lightweight Pollen Grains**: The pollen grains are light and dry, which helps them to be carried easily by the wind.
- **Non-Sticky Pollen**: The pollen grains are non-sticky, which prevents them from clumping together and allows them to be dispersed over a larger area.
- **Large Quantity of Pollen Production**: These plants produce a large number of pollen grains to increase the chances of successful fertilization.

4. **Evaluating the Options**:
- Now, we need to evaluate the options provided:
- **1. Pea**: Peas are typically self-pollinated and do not have feathery stigmas.
- **2. Wheat**: Wheat is a wind-pollinated plant and has feathery stigmas that help in capturing pollen.
- **3. Dhatura**: Dhatura is primarily pollinated by insects and does not have feathery stigmas.
- **4. Sizzle Pea**: This plant is also not known for having feathery stigmas.

5. **Conclusion**:
- Based on the characteristics of wind-pollinated plants and the evaluation of the options, the correct answer is **2. Wheat**.
