Chapter 4 Lesson 2
| Term | Definition |
|---|---|
| Tissue | A group of single cell that performs a specific function. |
| Organ | Is made up of different tissues. |
| Radial symmetry | A body plan in which any number of imaginary lines can be drawn through a central point to divide it into two mirror images |
| Bilateral symmetry | A body plan in which a single imaginary line divides the body into left and right side that our mirror images of each other. |
| Describe an animals body plan | tissues, organs, and organ systems. |
| Describe how the structure of animals are related to their symmetry. | Animals with out symmetry=simple, special cells, no tissues Radial symmetry = complex body plan , with tissues, with organ system. Bilateral symmetry equals organ systems |
| Describe what asymmetrical body type means and give an example of an animal | They have no symmetry, for example most sponges |
| Describe what asymmetrical body type means and give an example of an animal | They have no symmetry, for example most sponges |
| Describe what radial body symmetry means and give an animal example | an animal has many Imaginary lines can be drawn through a central point to divide into two mirror images example a jellyfish. |
| Describe what bilateral body symmetry means and give an example of an animal | an animal with only one line of symmetry can be drawn to divide it into halves that are mirror images.. |
