Which type of aestivation is found in Pea?

Answer

**Step-by-Step Solution:**

1. **Understanding Aestivation**: Aestivation refers to the arrangement of petals in a flower bud before it opens. Different types of aestivation can be observed in various flowering plants.

2. **Identifying the Plant**: The question specifies the pea plant (Pisum sativum). To answer the question, we need to focus on the characteristics of the flower structure of the pea plant.

3. **Observing the Petal Arrangement**: In the pea plant, the flower has a specific arrangement of petals. There are five petals in total: one large standard petal, two wing petals, and two smaller keel petals.

4. **Describing Vexillary Aestivation**: In vexillary aestivation, the larger petals (the standard) surround the smaller petals (the wings and keel). This arrangement is unique and allows the larger petals to protect the smaller ones before the flower opens.

5. **Comparing with Other Types of Aestivation**:
- **Valvate**: No petals overlap; they touch at the edges.
- **Twisted**: Petals are twisted over one another.
- **Imbricate**: Petals overlap but not in a uniform manner.
- **Quinquelateral**: A specific arrangement where one petal is surrounded by others in a distinct pattern.

6. **Concluding the Answer**: Based on the arrangement of petals in the pea plant, we conclude that the type of aestivation found in pea is **vexillary aestivation**.

**Final Answer**: Vexillary aestivation is found in the pea plant.
