Which of the following is not actinomorphic (radially symmetry)?

Options

A. Mustard
B. Datura
C. Chilli
D. Gulmohar

Answer

To determine which of the following options is not actinomorphic (radially symmetrical), we need to understand the definitions of actinomorphic and zygomorphic flowers.

### Step-by-Step Solution:

1. **Understand Actinomorphic Flowers**:
- Actinomorphic flowers are those that can be divided into two equal halves in multiple planes. This means if you draw lines from the center of the flower, you can create symmetrical halves regardless of the angle of the line.
- Common examples include flowers like hibiscus and daisy.

2. **Understand Zygomorphic Flowers**:
- Zygomorphic flowers, on the other hand, can only be divided into two equal halves by a single plane. This means there is only one way to cut the flower to achieve symmetry.
- Examples include flowers like pea and gulmohar.

3. **Analyze the Options**:
- If provided with a list of flowers, identify which of them are actinomorphic and which are zygomorphic.
- For instance, if the options include flowers like hibiscus (actinomorphic), daisy (actinomorphic), and gulmohar (zygomorphic), we can conclude that gulmohar is not actinomorphic.

4. **Select the Correct Answer**:
- Based on the analysis, the flower that is zygomorphic (and thus not actinomorphic) should be selected as the answer. In this case, the answer is option number 4 (assuming it corresponds to gulmohar).

### Conclusion:
The flower that is not actinomorphic is option number 4.
