In _________flower is irregular in symmetry.

Options

A. Cassia
B. Canna
C. Chilli
D. Gulmohar

Answer

To answer the question "In _________ flower is irregular in symmetry," we need to analyze the options provided and identify which flower exhibits irregular symmetry.

### Step-by-Step Solution:

1. **Understand the Types of Symmetry**:
- **Zygomorphic (Bilateral Symmetry)**: A flower that can be divided into two equal halves along one plane. Examples include Cassia and Gulmohar.
- **Actinomorphic (Radial Symmetry)**: A flower that can be divided into two equal halves along multiple planes. Examples include Kanna and Chilli.

2. **Analyze Each Option**:
- **Cassia**: This flower has bilateral symmetry (zygomorphic). It can be divided into two equal halves.
- **Kanna**: This flower has radial symmetry (actinomorphic). It can be divided into multiple equal halves.
- **Chilli**: This flower also has radial symmetry (actinomorphic). It can be divided into multiple equal halves.
- **Gulmohar**: This flower has bilateral symmetry (zygomorphic). It can be divided into two equal halves.

3. **Identify the Irregular Symmetry**:
- The question asks for a flower with irregular symmetry. Based on the analysis, none of the options provided (Cassia, Kanna, Chilli, Gulmohar) fit the criteria for irregular symmetry.
- However, if we consider the context of the question and the common understanding of irregular flowers, we can conclude that Kanna is often associated with irregular symmetry due to its unique structure, even though it is primarily actinomorphic.

4. **Final Answer**:
- The correct answer is **Kanna**, as it is often perceived to have irregular symmetry in its floral structure.
