Chapter 8 and Chapter 9 Vocab Words
Classification=The division of organisms into groups, or classes, based on specific characteristics
Taxonomy=The science of describing, naming, and classifying organisms
Dichotomous Key=An aid that is used to identify organisms and that consist of the answers to a series of questions
Genus=In classification of organisms, this is a subdivision of a family, usually consisting of more than one species.
Scientific Naming (Binomial Nomenclature)=Developed by Linnaeus as a way to give each species a two-part scientific name. The first part of the name is the genus name. The second part of the name is the specific part.
Prokaryote=Single-celled organisms that do not have a nucleus or membrane-bound organelles, but do have DNA and ribosomes. These organisms live almost everywhere.
Eukaryote=All organisms whose cells have a nucleus and membrane-bound organelles.
Species=A group of organisms that are closely related and can mate to produce fertile offspring
Kingdom=The second highest taxonomic group into which organisms are grouped. There are 6 different categories: Animalia, Plantae, Fungi, Protista, Eubacteria, and Archebacteria
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.
Plantae=A kingdom consisting of organisms that are eukaryotic, have cell walls, and make food through photosynthesis.
Animalia=A kingdom made up of complex, multicellular organisms that lack cell walls, can usually move around, and quickly respond to their environment.
Archaea=A type of prokaryote that has a different cell wall than other organisms. These organisms live in extreme environments, where no other organisms could live (extremophiles)
Bacteria=The smallest cells known, live almost anywhere, and do not have a nucleus.
Protista=A kingdom of single-celled or simple multicellular organisms. Include protozoans and algae..
