discipline of classifying organisms and assigning each organism a universally accepted name
taxonomy
system in which each species receives two names
binomial nomenclature
first part of binomial nomenclature
italicized, capitalized, Genus
group of closely related species
genus
second part of binomial nomenclature
italicizes, not capitalized, species
who made the system of classifcation that has 7 hierachy levels?
Linnaeus
Seven classifcation levels largest to smallest
Kingdom Phylum Class Order Family Genus Species
two kingdoms in Linnaeus's system of classification
Animalia and Plantae
the study of evolutionary relationships among organisms
phylogeny
biologists now group organisms into categories that represent ________________ not just physical similarities
evolutionary descent
all members of a ______ share a common ancestor
genus
organisms that appear very similar may not share a ________________ this is because of _______
recent common ancestor, natural selection
method that identifies and considers only those characteristics of organisms that are evolutionary innovations- new characteristics that arise as lineages evolve over time
cladistic analysis
characteristics that appear in recent parts of a lineage but not in its older members
derived characters
diagram that shows the evolutionary relationships among a group of organisms
cladogram
the six-kingdom system of classification includes the systems
Animalia, Plantae, Fungi, Protista, Eubacteria, Archaebactera
before Linnauese, scientific names were problematic because they were
very long and difficult to standarize
in taxonomy, a group at any level or organization is referred to as a
taxon
streptoccocus is a prokaryotic cell and belongs to the kingdom
Eubacteria
Which of the following organisms would have cell walls containing peptidoglycan?
yeast
carnations
e coli
paramecium
E COLI
a more inclusive category than any other - larger than a kingdom

archaea, bacteria, eukarya
domain bacteria
(mode of getting food/energy)
chemosynthetic+ + photosynthetic
domain bacteria --> pro/eukaryotic; multi/unicellular
unicellular, prokaryotic
domain bacteria --> cell walls?

domain archaea --> live in what kind of environments?
live in harsh conditions; boiling springs, volcanoes
domain archaea --> anaerobic or aerobic?
most are anaerobic
form of nutrition? --> archaebacteria
chemosynthesis
archaea can be seen in ______
large clusters
example of archaebacteria

older
archae bacteria ____ contain peptidoglycan in their cell walls
don't
archae bacteria have ________ in their cell membranes not found in many other organisms
unusual lipids
another example of eubacteria
e coli
this domain consists of all organisms that have a nucleus
Eukarya
kingdom that is composed of the greatest variety of organisms
protista
protista are unicellular or multicellular?
both
members of this kingdom are heterotrophs that feed on dead or decaying matter
fungi
fungi are unicellular or multicelular?
both
