Assertion :- Pea flowers are zygomorphic.
Reason :-Pea flowers can be cut in two equal halves by any radial plane passing through the centre.

Options

A. If both Assertion & Reason are True & Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Pea flowers are zygomorphic."
- **Explanation**: Zygomorphic flowers exhibit bilateral symmetry, meaning they can only be divided into two mirror-image halves in one specific plane.

2. **Understanding the Reason**: The reason states that "Pea flowers can be cut into two equal halves by any radial plane passing through the center."
- **Explanation**: This statement is incorrect for zygomorphic flowers. Zygomorphic flowers, like pea flowers, cannot be divided into equal halves by any radial plane. Instead, they can only be divided in one specific way, typically along a vertical plane.

3. **Identifying the Type of Symmetry**:
- **Zygomorphic Symmetry**: As mentioned, pea flowers have zygomorphic symmetry, which means they have bilateral symmetry.
- **Actinomorphic Symmetry**: The reason describes actinomorphic flowers, which can be divided into equal halves by any radial plane. Examples include mustard flowers.

4. **Conclusion**:
- The assertion is true because pea flowers are indeed zygomorphic.
- The reason is false because it describes a characteristic of actinomorphic flowers, not zygomorphic ones.

5. **Final Answer**: Therefore, the correct conclusion is that the assertion is true, and the reason is false.
