The flower of which of the following plant is zygomorphic?

Options

A. Bean
B. Datura
C. Mustard
D. Canne

Answer

To determine which plant has a zygomorphic flower, we need to understand what zygomorphic means. Zygomorphic flowers are those that can be divided into two equal halves in only one plane, while actinomorphic flowers can be divided into two equal halves in multiple planes.

Here is a step-by-step solution:

1. **Understand the Definition of Zygomorphic Flowers**: Zygomorphic flowers have bilateral symmetry, meaning they can be divided into two mirror-image halves along one specific plane.

2. **Identify the Options**: The options given are:
- Bean
- Datura
- Mustard
- Cane

3. **Analyze Each Option**:
- **Bean**: The flower of the bean plant can be divided into two equal halves along one plane. Thus, it is zygomorphic.
- **Datura**: The flower of Datura exhibits radial symmetry and can be divided into equal halves in multiple planes. Therefore, it is actinomorphic.
- **Mustard**: Similar to Datura, mustard flowers also have radial symmetry and are actinomorphic.
- **Cane**: The flower of the cane plant does not exhibit any symmetry when divided, making it asymmetrical.

4. **Conclusion**: Based on the analysis, the flower that is zygomorphic is the **Bean**.

**Final Answer**: The flower of the Bean plant is zygomorphic.
