ORGANISM CLASSIFICAT
6.12CD CLASSIFICATION OF ORGANISMS
Term | Definition |
---|---|
TAXONOMY | Branch of science that formally names & classifies organisms by their structure, function, & relationships. |
STRUCTURE | Arrangement of parts that form a living thing. |
FUNCTION | What something does. |
EUKARYOTIC CELL | Cell with a nucleus & membrane-bound organelles. |
PROKARYOTIC CELL | Cell lacking a nucleus or any other membrane-enclosed organelle. |
UNICELLULAR ORGANISM | Organism made up of 1 cell. |
MULTICELLULAR ORGANISM | Organism made up of more than 1 cell & often made up of different types of cells. |
AUTOTROPH | Organism that obtains its nutrition from simple, inorganic compounds. |
HETEROTROPH | Organism that's unable to make its own food from simple inorganic molecules. |
REPRODUCTION | Process by which organisms produce more of their own kind. |
SEXUAL REPRODUCTION | Reproductive process involving 2 parents whose genetic material is combined to produce a new organism different from themselves. |
ASEXUAL REPRODUCTION | Method of reproduction that requires only 1 parent. |
DOMAINS | Highest level of the taxonomic hierarchy; includes 3 groups: Archaea, Bacteria, & Eukarya. |
DOMAIN BACTERIA | 1 of 3 taxonomic domains; includes prokaryotic, single-celled organisms that lack a membrane-enclosed nucleus & that can be classified by shape. |
DOMAIN ARCHAEA | 1 of 3 taxonomic domains; includes unicellular prokaryotic organisms, like bacteria, but also share characteristics w/eukaryotes. |
DOMAIN EUKARYA | 1 of 3 taxonomic domains of organisms; cells contain a membrane-enclosed nucleus. |
KINGDOMS | 2nd highest level in taxonomic hierarchy; contains 6 groups: Archaea, Bacteria, Protista, Fungi, Plantae, & Animalia. |
KINGDOM BACTERIA | Kingdom of prokaryotic, single-celled organisms that lack a membrane-enclosed nucleus & can be classified by shape. |
KINGDOM ARCHAEA | Kingdom of unicellular organisms that are prokaryotic, like bacteria, but also share characteristics with eukaryotes. |
KINGDOM PROTISTA | Kingdom of single-celled & simple multiple-celled eukaryotic organisms. |
KINGDOM FUNGI | Kingdom of heterotrophic eukaryotes that reproduce through asexual spores & have chitin in their cell walls. |
KINGDOM PLANTAE | Kingdom of autotrophic eukaryotes that includes all plants. |
KINGDOM ANIMALIA | Kingdom of heterotrophic eukaryotes that includes all animals. |
