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
