Taxonomy Groups
Term | Definition |
---|---|
cell | the smallest unit of an organism that preforms life functions |
nucleus | a structure found in eukaryotic cells that contain DNA and is responsible for controlling the activities of the cell |
Eukaryotic | a cell containing a membrane-enclosed nucleus and organelles |
Prokaryotic | a cell locking a nucleus or any other membrame-enclosed organelles |
unicellular | an organism made up of one single cell |
multicellular | an organism made up of more than one cell, and often made up of different types of cells |
clssification | the process of grouping things based on similarities |
taxonomy | the branch of science that formally names and classifies organisms bby their structures |
Domain | the highest and largest rank of grouping organisms Three groups : Archaea, Bacteria, and Eukaryotic |
Domain Bacteria | Prokaryotic single-celled organism that lacks a nucleus in its cell |
Domain Archaea | prokaryotic single-celled organism that lacks a nucleus in its cell and can live in extreme environments |
Domain Eukarya | organisms with cells that contain a nucleus |
Kingdom | a taxonomic rank below Domain 6 Groups: Animalia, Fungi, Plantae, Protista, Archaea, and Eubacteria |
autotroph | an organism that is able to make its own food: known as a producer in the food chain |
heterotroph | an organism that CANNOT make its own food: known as a consumer in the food chain |
asexual reproduction | a method of reproduction that requires only one parent 100% DNA from 1 parent |
sexual reproduction | a method of reproduction that requires both Male and Female 50% from one parent 50% from one parent |
cell theory | states that all living organisms are made up of 1 or more cells; cells are the basic unit of life and all cells come from other cells |
Kingdom Archeabacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in extreme environments |
Kingdom Eubacteria | unicellular, asexual, auto and Heterotroph, prokaryotic organism that live in moderate environments |
Kingdom Protista | uni- and multicellular sexual or asexual auto- and heterotrophic eukaryotic organism that are microsopic |
Kingdom Fungi | uni- and multicellular sexual or asexual, heterotrophic, eukaryotic organism; known as a decomposer in the food chain |
Kingdom Plantae | multicellular, sexual and asexual, autotrophs, eukaryotic organism; known as a producer in the food chain |
Kingdom Animilia | multicellular, sexual and asexual, heterotrophs, eukaryotic organisms;known as a consumer in the food chain |
