Differentiate between Radially symmetrical and bilaterally symmetrical organisms

Explanation

To differentiate between radially symmetrical and bilaterally symmetrical organisms, we can break down the characteristics of each type of symmetry step by step.

### Step 1: Definition of Radial Symmetry
- **Radial Symmetry**: Organisms with radial symmetry can be divided into similar halves by multiple planes that pass through a central axis. This means that if you cut the organism in any direction through the center, you will get two equal halves.

### Step 2: Definition of Bilateral Symmetry
- **Bilateral Symmetry**: Organisms with bilateral symmetry can only be divided into two equal halves by a single vertical plane that divides the body into left and right sides. This means that there is only one way to cut the organism to achieve two equal halves.
