Classification

the division of organisms into groups, or classes, based on specific characteristics

the science of describing, naming, and classifying organisms

an aid that is used to identify organisms and that consists of an answer to a series of questions

kingdom made up of bacteria that live in extreme environments

kingdom that consists of all prokaryotes except Archaebacteria

a kingdom of mostly one-celled eukaryotic organisms that are different from plants, animals, bacteria and fungi

a kingdom made up of non-green eukaryotic organisms that have no means of movement, reproduce by using spores, and get food by breaking down substances in their surroundings and absorbing the nutrients

a kingdom made up of complex, multicellular organisms that are usually green, have cell walls made of cellulose, cannot move around, and use the sun's energy to make sugar by photosynthesis

a kingdom made up of complex, multicellular organisms that lack cell walls, can usually move around, and quickly respond to their environment

Swedish scientist; in the 1700's, created the seven levels of classification that are still used today

system that gives each organism a two part (scientific name) using the organism's Genus & species

a taxonomic category that ranks above species (organisms in this group are very closely related).

organisms that can mate and produce fertile offspring (the most specific taxonomic category)
