the process of grouping things based on their similarities
the scientific study of how organisms are classified AND named
organize living things into groups so that the organisms are easier to study
Biologists use classification to...
Who invented the naming system called binomial nomenclature?
the placement of organisms into groups based on observable features. Each organism was given a unique two-part name. genus - 1st part; descriptive - 2nd part often describes where an organism lives or its appearance
the first word in an organism's scientific name. classification grouping that contains similar, closely related organisms
a group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce
it is written in italics and it is Latin
How is a scientific name written?
Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species
List the levels of classification in order from biggest to smallest.

unicellular organisms whose cell lacks a nucleus and are members of domain Bacteria;
In the very bottom of the pacific ocean
Where do organisms in the domain Archaea live?
organisms with cells that contain nuclei and are in the Eukarya domain - can be unicellular or multicellular
protists, fungi, plants, or animals
What four kingdoms can eukaryotes be distributed?
the more characteristics they have in common and the more closely they are related
The more classifications levels two organisms share...
consists of a series of paired statements that describe the physical characteristics of different organisms
By choosing one statement in each pair of taxonomic keys and following its directive, the identity of an unfamiliar organism can eventually be determined.
How are taxonomic keys used?
Bacteria, Archaea, Eukarya
What are the three domains?
dense area in a cell that contains nucleic acids which are chemicals that direct all of a cell's activities
Both are unicellular prokaryotes that can be autotrophs or heterotrophs BUT their chemical makeup is different and the structure of their cells
Compare Bacteria and Archaea
"odds and ends" kingdom because it includes any eukaryote that cannot be classified in an animal, plant, or fungus
What is a nickname for the protist kingdom?
mushrooms, molds, mildew - most feed by absorbing nutrients from dead or decaying organisms
members of the fungi kingdom
autotrophs that can make their own food
All members of plant kingdom are
heterotrophs that have different adaptations that allow them to locate food, capture it, eat it, and digest it.
All members of animal kingdom are
