In pea flowers, there are five petals, the largest (A) overlaps the two lateral petals (B) which in turn overlap the two smallest anterior petals (C). Name A, B and C

Options

A. C-standard, B-wings, A-keel
B. B-standard, A-wings, C-keel
C. A-standard, B-wings, C-keel
D. C-standard, A-wings, B-keel

Answer

To solve the question regarding the naming of the petals in pea flowers, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Pea Flowers**:
- Pea flowers have a specific arrangement of petals known as vexillary estivation. This means that the petals are arranged in a particular overlapping pattern.

2. **Identifying the Largest Petal (A)**:
- In the pea flower, the largest petal is the one that stands out the most. This petal is referred to as the **Standard**.

3. **Identifying the Lateral Petals (B)**:
- There are two lateral petals that are smaller than the standard petal. These petals are known as the **Wings**. They are positioned on either side of the standard petal.

4. **Identifying the Smallest Anterior Petals (C)**:
- The smallest petals, which are located at the front of the flower, are called the **Keel**. These petals are often fused together and are situated beneath the standard and wings.

5. **Final Naming**:
- Based on the above identification:
- A (the largest petal) is called the **Standard**.
- B (the two lateral petals) are called the **Wings**.
- C (the smallest anterior petals) is called the **Keel**.

### Conclusion:
Thus, the names of the petals in the pea flower are:
- A: Standard
- B: Wings
- C: Keel
