| Difference Between Radial And Bilateral Symmetry |
|
Definition
Radial symmetry is when parts of the body are arranged around a central axis.
Bilateral symmetry is when the body can be divided into left and right halves along only one plane |
|
|
Term
| Why is bilateral symmetry advantageous? |
|
Definition
1. Allows parts of the body to evolve in different ways permitting segregation of organs in different parts of the body
2. Allows for more efficient movement and response to stimuli
3. Centrally located brain allows for more control of the rest of the body |
