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 |
Eukaryatic | a cell containing a membrane - enclosed nucleus and organells |
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 Three groups: Archaea, bacteria, and Eukarya |
Domain | the highest and largest rank of grouping organisms Three groups: Archaea, Bacteria, and Eukaray |
Domain Bacteria | prokaryotic , single-celled organisms that lacks a nucleus in its cell |
Domain Archaea | prokarayotic, single-celled organisms 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 tank 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 |
hetertroph | an organism that CANNOT make its own food; known as a consumer in the food chain |

sexual | a method of reproduction that requires both male and female parent 50% from 1 parent 50% from 1 parent |
cell theory | states that all living organisms are made of 1 or more cell; cell are the basic unit of life and all cells come from other cells |
kingdom archeabateria | 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 microscopic |
kingdom fungi | uni- and multicellular sexual or asexual, heterotrophic, eukaryotic organism; known as a decomposer in the food chain |
