what is the correct order for the levels of the Linnaeus classification system from general to specific?
Domain, kingdom, phylum, class, order, family, genus, species.
What are the 3 Domains? (Examples)
Bacteria - E.Coli/Strep
Archaea - Chemo-synthetic
Eukarya - Plant/Animalia
How are prokaryotes and eukaryotes different?
Pro has no nucleus (pro = before0
What makes the Archaea domain so unusual?
They can survive in extreme environments
What is the most abundant group of organisms on earth?
Bacteria
List/Describe the Kingdoms in the most current tree of life
Animalia - Apes/Humans Plants - moss/grass Bacteria - E.Coli Fungi - mushrooms Protists - algae/photosynthetic/protazoa Archaea - extremophiles
Which Kingdoms have organisms with cell walls/ how are the cell walls different?
Plant - cell walls composed of cellulose
Fungi - cell walls composed of chitin
Bacteria - cell walls composed of peptidoglycan
How are most scientific names selected? How are they written?
Physical Characteristics (description) - written in Latin

Binomial Nomenclature
Two terms are used to denote a species of living organism - system of naming
Taxonomy
Branch of science concerned with classification
Chitin
Main substance in cell walls of fungi and exoskeletons on anthropods
Peptidoglycan
Main substance in the cell walls of bacteria
Extremophile
Microorganism that lives in an environment of extremes
Autotroph
Organism that makes its own food
Heterotroph
Organism that must get its food from eating other things
Chemotroph
Organisms that obtain energy by the oxidation of electron donors in its environment
