Life Science

TermDefinition
species a group of organisms that are closely related and can mate to produce fertile offspring
genus the level of classification that comes after family and that contains similar species
domain In a taxonomic system, one of the three broad groups that all living things fall into
Bacteria a domain made up of prokaryotes that usually have a cell wall and that usually reproduce by cell division
Archaea a domain made up of prokaryotes, most of which are known to live in extreme environments, that are distinguished from other prokaryotes by differences in their genetics and in the makeup of their cell walls
Eukarya in a modern taxonomic system, a domain made up of all eukaryotes; this domain aligns with the traditional kingdoms Protista, Fungi, Plantae, and Animalia
Protista a kingdom of mostly one-celled eukaryotic organisms that are different from plants, animals, archaea, bacteria, and fungi
Plantae a kingdom made up of complex, multicellular organisms that are usually green, have cell walls made of cellulose, cannot move, and use the Sun's energy to make sugar by photosynthesis
Fungi a kingdom made up of non-green, eukaryotic organisms that have no means of movement, reproduce using spores, and get food by breaking down substances in their surroundings and absorbing the nutrients
Anamalia a kingdom made up of complex, multicellular organisms that lack cell walls, can usually move around, and quickly respond to their environment
