---|---|
Cell | The smallest unit of an organism that performs life functions |
Nucleous | 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 one single cell |
Musticellular | 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 |
Taxononmy | The branch of science that formally names and classifies organisms by their structure,function and relationship |
Domain | The highest and largest rank of grouping 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 lacs a nucleus in its cell and can live in extreme enviroments |
Domain Eukarya | Organisms with cells that contain a nucleus |
Kingdom | A taxonomic rank below domain 6 groups:animal,fungi,plantae,protista,archaea,and eubacteria |
Autotroph | An organism that is able to make its own food;known as a producer in the chain of food |

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 organisms that live in extreme enviroments |
Kingdom Eubacteria | Unicellular,asexual,auto and heterotroph,prokaryotic organisms that live in moderate enviroments |
Kingdom Protista | Uni-and multi cellular sexual or asexual auto-and heterotrophic eukaryotic organism that are mocroscopic |
Kingdom Fungi | Uni-and multicellular sexual and asexual,heterotrophic,eukaryotic organism;known as a decomposer in the food chain |
