To study the diversity of life, biologists use a - system to name organisms and group them into a logical manner
|
classification
|
|
|
scientists classify organisms and assign each organism a universally accepted name
|
Taxonomy
|
|
|
a two-term naming system
|
bionomical nomenclature
|
|
|
a Swedish botanist who lived during hte eighteenth century and developed a two-term naming system
|
Linnaeus
|
|
|
group of closely related species
|
genus
|
|
|
Linnaeus's hierarchial system of classification includes - levels
|
seven
|
|
|
levels of classification from largest to smallest
|
Kingdom, Phylum, Class, Order, Family, Genus, Species
|
|
|
genera that share many chatacteristics are grouped in a larger category
|
family
|
|
|
a broad taxonomic category composed of similar families
|
order
|
|
|
composed of similar orders
|
class
|
|
|
several different classes make up a-. It includes many different organisms that nevertheless share important characteristics
|
phylum
|
|
|
the largest and most inclusive of linnaeus's taxonomic categories
|
kingdom
|
|
|
evolutionary relationships among organisms
|
phylogeny
|
|
|
Biologists now group organisms into categories that represent lines of - - , not just physical similarities
|
evolutionary descent
|
|
|
the strategy of grouping organisms together based on their evolutionary history
|
evolutionary classification
|
|
|
characteristics that appear in recent parts of a lineage but not in its older members
|
derived characters
|
|
|
derived characters can be used to construct a -
|
cladogram
|
|
|
The six-kingdom system of classification includes the kingdoms:
|
Eubacteria, Archaebacteria, Protista, Fungi, Plantae, and Animalia
|
|
|
more inclusive category than any other- larger than a kingdom
|
domain
|
|
|
the 3 domains
|
Eukarya, Bacteria, and Archaea
|
|
|
Domain composed of protists, fungi, plants and animals
|
Eukarya
|
|
|
Domain corresponds to the kingdom Eubacteria
|
Bacteria
|
|
|
domain which corresponds to the kingdom Archaebacteria
|
Archaea
|
|
|
members of the domain - are unicellular and prokaryotic
|
Bacteria
|
|
|
Members of the domain - live in some of the most extreme environments you can imagine- volcanic hot springs, brine pools, and black organic mud totally devoid of oxygen
|
Archaea
|
|
|
the kingdom - is composed of eukaryotic organisms that cannot be classified as animals, plants, or fungi
|
Protista
|
|
|
The domain - consists of all organisms that have a nucleus
|
Eukarya
|
|
|
Members of the kingdom - are heterotrophs. most feed on dead or decaying organic matter
|
Fungi
|
|
|
Members of the kingdom - are multicellular organisms that are photosynthetic autotrophs
|
Plantae
|
|
|
Members of the kingdom - are multicellular and heterotrophic
|
Animalia
|
