kingdom made up of prokaryotes (most of which are known to live in extreme environments) that are distinuished from other prokaryotes
in a modern taxonomic system, a domain made up of prokaryotes that usually have a cell wall and that usually reproduce
in a taxonomic system based on rRNA analysis, one of the three broad groups that all living things fall into
1. in a traditional taxonomic system, a kingdom made up of all prokaryotes except members of the kingdom Archaebacteria; currently, biologists prefer to classify members of this kingdom into the domain Bacteria
in a modern taxonomic system, a domain made up of all eukaryotes; this domain aligns with the traditional kingdoms Protista, Fungi, Plantae, and Animalia
classification kingdom made up of nongreen, eukaryotic organisms that get food by breaking down organic matter and absorbing the nutrients, reproduce by means of spores, and have no means of movement
branching diagram that models the relationships by ancestry between different species or other taxonomic groups
classification kingdom made up of eukaryotic, multicellular organisms that have cell walls made mostly of cellulose, that have pigments that absorb light, and that supply energy and oxygen to themselves and to other life-forms through photosynthesis
group of organisms that are closely related and can mate to produce fertile offspring; also the level of classification below genus and above subspecies
- taxonomic classification below species that groups organisms that live in different geographical areas, differ morphologically from other populations of the species, but can interbreed with other populations of the species
the classification of living organisms in terms of their natural relationships; it includes describing, naming, and classifying the organisms
