| 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 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 organism three groups :Archaea bacteria and eukarya |
| bacteria | Prokeriotic single celled organism that lacks a nucleus in its cell |
| archaea | Prokeriotic single celled organism that lacks a nucleus inits cell and can live in extreme environment |
| eukarya | organism 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 know as a producer in food chain |
| heterotrouph | an organism that Cannot make its own food know as a consumer in the food chain |
| asexual | a method of reproduction that requires only only one parent 100% DNA from 1 parent |
| 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 organism are made up of 1 or more cells ;cells are the basic unit of life and all cells come from other cells |
| archeabacteria | unicellular asexual auto and heteortroph prokaryotic ,organism that live in extreme |
| eubacteria | unicellular asexual auto and heteortroph prokaryotic ,organism |
