cell | the smallest unit of an organism that performs life functions |
nucleus | a structure found in Eukaryota 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 one single cell |
Multicellular | an organism made up of more then one call, and often made up of dirrerent 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, functions and relationships |
Domain | the highest and largest rank of grouping organisms three groups : Archaea, bacteria, and eukara. |
domain bacteria | Prokaryotic, single celled organism that lacks a nucleus in its cell |
domain archaea | Prokaryotic, single celled organism that lacks a nucleus in it's cell and can live in extreme enviroments |
domain eukarya | organisms with cells contain a nucleus |
kingdom | a taxonomic rank below domain 6 groups: Animalia, Fungi, plantae, protitsta, archaea, and eubacteria |

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 enviroments |
kingdom protista | uni and multicellular sexual or asexual auto and heterotroph eukaryotic organism that are microscope |
kingdom Fungi | uni and multicellular sexual or asexual, heterotroph,eukaryotic organism; knowm as a decomposer in the food chain |
