| Term | Definition |
|---|---|
| cell | the smallest unit of an organism that performs life functions |
| nucleus | a structure found in Eukaryota 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 member-enclosed organelles |
| unicellular | an organism made up of one single cell |
| multicellular | an organism made up of one or more that 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 relationships |
| Domain | the highest and largest rank of grouping organisms three groups: Archean, Bacteria and Eukaryota |
| Domain bactearia | 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, planta,Protista,Archaea, and Eubacteria |
| autotroph | an organism that is able to make its own food; known as a producer in 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 reprodiction | a method of reproduction that requires both male and female parent 50% from one 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 calls come from other cells |
| kingdom Archeabacteria | unicellular asexual, auto and heterotroph, prokaryotic organism that live in extreme environments |
| Kingdom Eubacteria | unicellular, sexual,auto and hererotroph prokaryotic organism that live in moderate environments |
| kingdom Protista | uni- and multi cellular sexual auto- and heterotrophic Eukaryota organism that are microscopic |
| Kingdom Fungi | uni-and multi-cellular sexual or asexual, hetero-trophic,eukaryotic organism; known as a decomposer in the food chain |
| Kingdom Plantae | multi cellular, 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 |
