Radial symmetry is found in the flowers of
(a) Pisum
(b) Cassia
(c) Brassica
(d) Trifolium

Options

A. Pisum
B. Cassia
C. Brassica
D. Trifolium

Answer

To determine which flower exhibits radial symmetry, we can follow these steps:

### Step 1: Understand Radial Symmetry
Radial symmetry refers to a body plan in which parts are arranged around a central axis. In flowers, this means that the flower can be divided into equal halves by any vertical plane passing through the center.

### Step 2: Analyze the Options
We have four options to consider:
- (a) Pisum
- (b) Cassia
- (c) Brassica
- (d) Trifolium

### Step 3: Identify the Flower with Radial Symmetry
- **Pisum**: This flower does not exhibit radial symmetry; it has bilateral symmetry.
- **Cassia**: This flower also does not exhibit radial symmetry; it is typically bilaterally symmetrical.
- **Brassica**: Brassica flowers exhibit radial symmetry, meaning they can be divided into equal parts by multiple vertical planes. They are classified as actinomorphic flowers.
- **Trifolium**: This flower does not exhibit radial symmetry; it is also bilaterally symmetrical.

### Step 4: Conclusion
Based on the analysis, the flower that exhibits radial symmetry is **Brassica**.

### Final Answer
(c) Brassica
