| Describe an animals body plan. | The organization of an animal's cells into higher levels of structure, including tissues, organs, and organ systems. |

| Describe what an asymmetrical animal body type means and give an example of an animal. | Asymmetrical body type means that there is no way that it could be divided up into a mirror image. Ex.: sponge |
| Describe what radial body symmetry means and give an example. of an animal. | Radial symmetrical body type means that there are multiple ways of splitting it up into mirror image. Ex.: sea star |
| Describe what bilateral symmetry means and give an example of an animal. | Bilateral symmetrical body type means that there is only one way to split it up into a mirror image. Ex:. bird |
