Animal structures
Chapter four lesson 2
| Question | Answer |
|---|---|
| Tissue | A group of smilier cells that preform a specific function . |
| Organ | A body structure that is composed of different kinds of tissue that work together. |
| Radial symmetry | A body plan in which any number of imaginary lines the all pass through a central point divide the animal into two mirror images. |
| Bilateral symmetry | A body plan in which a sing imaginary line divides the body into left and right sides that are mirror images of each other. |
| describe an animal's body plan | The organization of an animal's cell into higher levels of structure, including tissue, organs, and organ systems. |
| describe how the structures of animals are related to their symmetry | The bodies animals without symmetry are organized simply, with some specialized cells but no tissues. In contrast, animals with radial symmetry have |
| complex body plans with tissues and usually with organ systems. Animals bilateral symmetry have organ systems | |
| Describe what asymmetrical body type means and give an example of an animal | Asymmetrical body type means that the left and right sides of your body are not mirror images of each other [ a example of a animal is a sponge] |
| Describe what radial body symmetry means and give an example. | radial body symmetry means animal symmetry in which similar parts are arranged in a balanced way around the center of the body compare bilateral symmetry. an example is jellyfish |
| describe what bilateral body symmetry means and give an example | It is when both sides of the animal can be divided into two halves and are mirror images of each other. And an example is a butterfly. |
