| 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 one 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 rank of grouping organisms three groups archaea,bacteria,and eukarya |
| 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 food chain |
