Biology Unit 1 Review
Diversity/Classification:
Taxonomy: the field of classification of organisms (use, morphology, physiology, DNA to
organize)
7 Taxons/Ranks (Goes from Largest/most broad-> smallest):
Hierahial Classifiatio
Domain (Archea, Bacteria, Eukaryota)
Kingdom (Archea, bacteria, protista fungi, plantae, Animalia)
-based on cellular organization; prokaryotes, eukaryotes; single or multicellular; method of
nutrition, absorb, ingest, produce
Phylum –based on body plan an organization
Class
Order
Family
Genus
Species
Subspecies
Species: a group of organisms that can interbreed and create fertile offspring
(Ex. Donkey and horse breed to make mule, but mule cannot make more mules)
Phylogeny: study of evolutionary relationships and ancestors (through phylogenetic tree)
Binomial Nomenclature:
Implemented by Carl Linnaeus:
- In order to make standard naming system
-help keep track, easier to remember and classify
-show relations, evolution, compare species
-identify traits of organisms
