LAYFIELD’S GMAS STUDY GUIDE SERIES – STUDY GUIDE #2: CLASSIFICATION 1. 2. 3. 4. 5. 6. What is a dichotomous key? A series of paired statements used to identify organisms How many identifying statements are there in each step of a dichotomous key? 2 What is binomial nomenclature (what does it mean)? A two-part naming system Who came up with binomial nomenclature? Linnaeus What is the first part of a scientific name? The second part? 1st – GENUS, 2nd - SPECIES What are the levels of classification (King Philip Came Over For Good Spaghetti)? KINGDOM, PHYLUM, CLASS, ORDER, FAMILY, GENUS, SPECIES 7. How is a species defined? (How do you know if two organisms are the same species?) Members of a species are able to successfully reproduce and produce viable offspring. 8. What is the difference between a prokaryotic and eukaryotic cell? Prokaryote – No Nucleus, Eukaryote – Has a Nucleus 9. What is the difference between unicellular and multicellular? Uni – One Cell, Multi – Many cells 10. What is the difference between an autotroph and a heterotroph? Autotroph – Can create its own food from sun using photosynthesis, Heterotroph – has to get food from another source 11.
