| Term | Definition |
|---|---|
| Cell | the smallest unit of an organism that performs life functions |
| nucleus | a structure found in eukaryotic cells that contain DNA |
| eukaryotic | a cell containing a membrane- enclosed nucleus and organelles |
| prokaryotic | a cell lacking a nucleus or any other membrane enclosed organellas |
| 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 organism by there structure function and relationship |
| domain | the highest and largest rank of grouping organisms three groups Archae bacteria and eukarya |
| domain bacteria | prokaryotic, single celled organism that lacks a nucleus in its cells |
| domain archaea | prokaryotic , single celled organism that lacks a nucleus in its cell and can live in extreme environments |
| domain eukarya | organism with cells that contain a nucleus |
| kingdom | a taxonomic rank below domain |
| autotroph | an organism that is able to make its own food; known as a producer in the food chain |
| heterotroph | an organism that CANNOT make its own food; known as a consumer in the food chain |
| asexual reproduction | a method of reproduction that requires only one parent 100% DNA from 1 parent |
| sexual reproduction | a method of reproduction that requires both male and female parent 50% from 1 and 50% from 1 parent |
| 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, prokayotic organism that live in moderate environments |
| kingdom protista | uni- and multicellular sexual or asexual auto- and heterothopic eukaryotic organism that are microscopic |
