Term | Definition |
cell | the smallest unit of an organism that performs 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 lacking a nucleus or any other membrane-enclosed organelles |
unicellular | an organism made up of a single cell |
multicellular | an organism made up of more than one cell and often made up of different types of cells |
classification | the process of grouping things based on similarities |
taxonomy | the branch of science that formally names and classifies organisms by their structure ,function, and relationship |
Domain | the highest and largest ranking grouping organisms that |
Domain Bacteria | prokaryotic,single celled organisms that lack a nucleus in its cell |
Domain Archaea | prokaryotic ,single celled organisms that lack a nucleus in its cell;can live in extreme environments |
Domain Eukarya | organisms with cells that have a nucleus |
kingdom | a taxonomic rank below Domain,6 Groups:Animalia,Fungi,Plantae,Protista ,and Bacteria |
heterotroph | an organism that cannot make its own food;known as a consumer in the food chain |
autotroph | an organism that can make its own food known as producer in the food chain |

cell theory | states that all living things are made up of 1 or more cells; cells are the basic unit of life and all cells come from other cells |
