8. 1) To explain how scientists classify living things 2) To identify the 6 kingdoms of life

9. Taxonomy The science of classification Based on common characteristics All living things are grouped into 3 Domains Under Domains there are 7 other levels

10. Levels of Classification Domain is the largest level Species is the smallest level The more levels that are the same, the more closely related 2 organisms are Together, Genus and species make up the scientific name Ex. Homo sapiens

13. Domains Archaea Bacteria Eukarya

15. Bacteria are grouped into 2 Domains Domain: Archaea Kingdom: Archaebacteria Unicellular Found in extreme environments Domain: Bacteria Kingdom: Eubacteria Unicellular Common

16. 4 Kingdoms of Eukarya

17. Organisms are put in different kingdoms based on: Can they make their own food? Autotrophic vs. Heterotrophic What type of cells? How complex? Prokaryotic vs. Eukaryotic Do they have a cell wall? How many cells? Unicellular (1) Multicellular (many)

18. Animalia Multicellular Heterotrophs – cannot make their own food

19. Plantae Multicellular Autotrophs – make their own food

20. Fungi Most are many cells Cannot make their own food Most are decomposers

21. Protists Left-overs Unicellular or Multicellular Things that are not fungi, bacteria, plants or animals
