1. Classification Chapter 9 Science 7

2. Classifications is the arrangement of organisms into orderly groups based on their similarities. Why Classify? –Because there are so many organisms that need to be organized so that scientists can answer important questions like: –How many species are there? –What are the characteristics of each? –What are the relationships between these species?

3. King Phillip Came Over For Grape Soda Levels of Classification

5. Common Names Every day names given to organisms. Problem: Common names do not describe the organism accurately. Taxonomy: The science of classification.

6. Modern Classification System Carolus Linnaeus: (1701-1778) Developed todays classification system that specifically identifies an organism using a two part scientific name. Genus species

7. Binomial Nomenclature “Two Names” Genus and Species Ex. Elephas maximus –“Indian” Genus –“elephant” Species Ex. Tyrannosaurus rex –“Tyrant lizzard” Genus –“king” species

8. Animalia Plantae Fungi Protista Eubacteria Archaebacteria

9. Single-celled Prokaryotic (no nucleus) Extremely small Live in hostile environments

10. Prokaryotic Single-celled Used in some of our foods. Ex. Turns milk into Yogurt Most common type of bacteria

11. Eukaryotic (Have nucleus) 2 Billion years old Single-celled Many different types: –Paramecium and Amoebas –Algae which are plant like protists –Slime molds which are fungus like protistes –Kelp are large multi- cellular protists

12. Eukaryotic Multicellular Absorbs nutrients from what they live on, they are NOT plants. 100,000 species

13. Autotrophic (Make their own energy through photosynthesis) Multicellular Eukaryotic 350,000 species

14. Eukaryotic Multicellular Most can move from place to place Must eat food for energy Have nervous system so they can react to their environment
