|---|---|
| Tissue | A group of similar cells that perform a specific function |

| radial symmetry | A body plan in which any number of imaginary lines that all pass through a central point divide that animal into two mirror images |
| bilateral symmetry | A body plan in which a single imaginary line divides the body into left and right sides that are a mirror images of each other |
| Animals body plan | The bodies of animals can be without symmetry or organized, with radial or bilateral symmetry. |
| How the structure of Animals are related to their symmetry | asymmetrical no symmetry, the simplest, only cells Radial cells and tissues ,Bilateral most complex ,has organ systems |
| asymmetrical body type | has no symmetry, ex = sponges |
| radial body symmetry | Multiple lines of symmetry, no front or back end ex= starfish |
| bilateral body symmetry | one line of symmetry ex= crab |
