| 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 |
| prokoryotic | 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 similsrities |
| 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 organisms, 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 lacks a nucleus in its cell and can live in extreme environments |
| domain eukarya | organisms with cells that contain a nucleus |
| kingdom | a taxonomic rank below domain, 6 groups animalia, fungi, plantea, protista, archeae, and eubacteria |
| autotroph | an organism that is able to make its own food; known as a consumer 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 parent 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 hetrotrophh prokaryotic organism that live in moderate environments |
| kingdom protista | uni- and multicellular sexual or asexual, auto- and hetrotrophic eukaryotic organism that are microscopic |
| kingdom Fungi | uni- and multicellular sexual or asexual, hetro trophic, eukaryotic organism ; known as a decompose in the food chain |
| kingdom Plantae | multicellular, sexual and asexual, autotrophs, eukaryotic organism; known as a producer in the food chain |
| kingdom Animilia | multicellular, sexual and asexual, hetrotrophs, eukaryotic organisms; known as a consumer in the food chain |
