1 Classifying Organisms Easier to Study!ClassificationThe process of grouping thing based on similarities.TaxonomyThe scientific study of how living things are classified
2 Naming Systems Aristotle Carolus Linnaeus 1707-1778 Carolus Linnaeus (Carl von Linné)Naming SystemsCarolus Linnaeus“Father of Taxonomy”Gave us system we use nowBinomial Nomenclaturetwo namesAristotle5AD---1st to ClassifyPlants VS Animalsherbs-shrubs-trees land-air-sea
3 Binomial Nomenclature 2 NamesGenus andSpeciesScientific NameWritten in italics. First word is capitalizedand the second is not. Homo sapiensIf handwriting the scientific name: Underline to show italics.
4 Genus Species Classification grouping that contains similar, closely related organismsSpeciesGroup of similar organismsthat can mate with eachother and produce offspringthat can also mate andReproduce.
5 Most biologists classify organisms into 8 levels. Broad to Specific More levels share more have in common

9 Domain Eukarya Fungi Plants Animals Protists Eukaryotic organism---cannot be classified as animal, plant or fungus---most unicellular---few multicellular—some autotrophs other heterotrophs.ProtistsFungiMulticellular eukaryotes. All heterotrophsPlantsMulticellular eukaryotes—most live on land----autotrophs---provide food for heterotrophsAnimalsMulticellular eukaryotes—live everywhere---hetertrophs
