The 7 Levels of Classification And the Six kingdoms King Phyl Aristotle 300’s BC • Classified organisms three ways; • Things that fly • Things that swim • Things that walk, crawl and run. King Phyl Carolus Linnaeus – 1750’s • Used observations for the basis of his system. • Observable features. • Came up with a naming system called binomial nomenclature (2 part name) • Used Latin, the language of scientists, species and genus. 7 Levels of Classification King Phyl Came Over For Great Spaghetti Kingdom Phylum Class Order Family Genus Species The Six Kingdoms Organisms are classified by: • Type of cell • Ability to make food • Number of cells in their body The 6 Kingdoms • • • • • • Archaebacteria Eubacteria Protists Fungi Plants Animals Archaebacteria • Unicellular • Prokaryotic – no organized nucleus • Autotrophs or heterotrophs • Thermoacidophile thrives in strongly acidic environments at high temperatures • Extreme halophiles – Thrives in salty environments. “Ancient or Old Bacteria” Eubacteria “New Bacteria” • Unicellular • Prokaryotic • Autotrophs or heterotrophs • Ex. Staphylococc us and E-coli. Protists –”odds and ends” • Unicellular or multicellular • Autotrophs or heterotrophs • Eukaryotic – organized nucleus • Ex. Amoeba, paramecium, slime molds, euglena, algae. Fungi • • • • • Most are multicellular Some are unicellular Eukaryotes Heterotrophs Feed on dead and decaying organisms • Sessile-cannot move on own. • Ex. Mushrooms, molds, mildew, yeast. Plant • Multicellular • Eukaryotes • Autotrophs • Sessile • Ex. Roses, magnolias. Animals • • • • Multicellular Eukaryotes Heterotrophs Motile-can move on own • Specialized sense organs So… to remember the kingdoms in correct order….. • Almost • Every • Person • Forgets • Passive • Agnes • • • • • • Archaebacteria Eubacteria Protists Fungi Plants Animals
