Classification & Identification Flashcards
What do you think is emphasized in medicine
Identification
Name the taxonomic hierarchy
Domain Kingdom (eukaryotes only) Phylum or division Class Order Family Genus Species
Name the three domains
Bacteria Archaea Eukaraya
Do you have to use binomial nomenclature to name species
Yes
What defines a prokaryotic species
A group of genetically related cells
Where did all cells arose from
A common prokaryotic ancestor 3.5 to 4 billion years ago
What is the eukaryotic cell evolution
Membrane infolding Endosimbiotic theory
What is taxonomy
The study of organisms to arrange them into groups for purposes of classification or identification
