The science of the classification of organisms.
|
Taxonomy
|
|
|
Subdivisions used to classify organisms
e.g. domain, kingdom, phylum |
Taxa
|
|
|
The science organizing groups of organisms into a hierarchy.
|
Systematics
|
|
|
The evolutionary history of a group of organisms; phylogenetic relationships are evolutionary relationships.
|
Phylogeny
|
|
|
All eukaryotes (animals, plants, fung, and protists); members of the domain Eukarya
|
eukarya
|
|
|
Domain of prokaryotic organisms, characterized by peptidoglycan cell walls
|
Bacteria
|
|
|
Domain of prokaryotic cells lacking peptidoglycan; one of the three domains.
|
Archea
|
|
|
The first name of the scientific name (binomial); the taxon between family and species.
|
Genus
|
|
|
The second or species name in a scientific binomial.
|
Specific Epithet
|
|
|
The system of having two names (genus and specific epithet) for each organism; also called scientifc nomenclature.
|
Binomial Nomenclature
|
|
|
A group of closely related organisms that can interbreed.
|
Eukaryotic Species
|
|
|
A taxonomic group between order and genus.
|
Family
|
|
|
A taxonomic group between class and family.
|
Order
|
|
|
A taxonomic group between phylum and order.
|
Class
|
|
|
A taxonomic classification between kingdom and class.
|
Phylum
|
|
|
A taxonomic classification between domain and phylum.
|
Kingdom
|
|
|
A taxonomic classification based on tRNA sequences and above the kingdom level.
|
Domain
|
|
|
A population of cells that share certain tRNA sequences; in conventional biochemical testing, it is a population of cells with similar characteristics.
|
Prokaryotic Species
|
|
|
A population of cells arising from a single parent cell.
|
Clone
|
|
|
Genetically different cells within a clone.
|
Strain
|
|
|
Term used for unicellular and simpe multicellular eukaryotes; usually protozoa and algae.
|
Protista
|
|
|
A group of organisms that share a particular common ancestor
|
Clades
|
|
|
a eukaryotic absorptive chemoheterotroph.
|
Fungi
|
|
|
The kingdom composed of multicellular eukaryotes with cellulose cell walls.
|
Plantae
|
|
|
The kingdom composed of multicellular eukaryotes lacking cell walls.
|
Animalia
|
|
|
A group of viruses sharing the same genetic information and ecological niche.
|
Viral Species
