Classification Classify objects according to a dichotomous key Identify similarities and differences among living organisms Vocabulary Classification – grouping things according to similar characteristics Characteristics – (Traits) internal or external structures or features Dichotomous Key – classifying things into two groups at a time Multicellular – made up of more than one cell Unicellular – made up of only one cell What is classification? Classification is the grouping of things according to similar__________________. Characteristics or traits We do this every day. How are items in your science room classified? 7 Groups Kingdom—least similar to each other Phylum Class Order Family Genus Species—most similar to each other King Phillip Came Over From Great Spain If two organisms have very few characteristics in common, they are most likely to be in the same species or kingdom? Why? Same kingdom because organisms of the same species are so similar they can reproduce to produce offspring and those in the same kingdom can not. Scientific Names First part is the genus they belong to. Second part is the species they belong to.
