Flowers are zygomorphic in :-

Options

A. Gulmohur
B. Tomato
C. Datura
D. Mustard

Answer

To determine which flower is zygomorphic among the given options, we need to understand the definitions and characteristics of zygomorphic and actinomorphic flowers.

### Step-by-Step Solution:

1. **Understand Flower Symmetry**:
- Flowers can be classified based on their symmetry into two main types: actinomorphic and zygomorphic.
- **Actinomorphic Flowers**: These flowers exhibit radial symmetry. They can be divided into two equal halves in multiple vertical planes. The parts of the flower are mirror images of each other.
- **Zygomorphic Flowers**: These flowers exhibit bilateral symmetry. They can only be divided into two equal halves in one vertical plane. They are considered irregular because they do not have mirror-image symmetry and often have unequal sizes of petals or sepals.

2. **Analyze the Given Options**:
- The options provided are: Gulmohur, Tomato, Datura, and Mustard.
- We need to identify which of these flowers is zygomorphic.

3. **Evaluate Each Flower**:
- **Gulmohur**: Known to have zygomorphic flowers due to their irregular shape and bilateral symmetry.
- **Tomato**: Typically has actinomorphic flowers, which are symmetrical and can be divided into equal halves in multiple planes.
- **Datura**: Also has actinomorphic flowers with radial symmetry.
- **Mustard**: Like tomato and datura, mustard flowers are actinomorphic.

4. **Conclusion**:
- Based on the characteristics of each flower, the only flower that is zygomorphic is **Gulmohur**.

### Final Answer:
The flowers are zygomorphic in **Gulmohur**.
