2. Characteristics of Animals
Multi-cellular
Heterotroph
Carnivore- eats meat
Herbivore- eats plants
Omnivore- eats meat and plants
Reproduce Sexually
Can move from place to place
Cells are eukaryote
Contains a nucleus

3. How Animal Cells are Organized
Bodies composed of many cells
Cells group together to form tissue
A group of cell that perform a specific function
Tissue may combine to form an organ
A group of tissues perform more complex functions then a tissue alone

4. How Animal Cells are Organized
Organs are made of four types of tissue
Organ systems
Different organs combine to form a system

5. How Animals Obtain Food
Heterotroph
Autotroph
Can not make own food
Must eat other organisms
Animals are not autotrophs
Animals eat autotrophs (plants)

13. Classification of Animals
Scientists classify animals in to groups
Each classification represents a shared characteristic.
Broader classification
Kingdom and Phylum
More specific classification
Species and genus
Based on
Structure of body
How embryo develops
DNA examination
