| Term | Definition |
|---|---|
| cell | the smallest unit of a organism that perform life function |
| 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 m=nucleus or any other membrane – enclosed organelles |
| unicellular | an organism made up of one singe 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 organisms – Three groups : Archaea, Bacteria, and Eukarya |
| Domain Bacteria | prokaryotic, single-celled organism that lack a nucleus in its cell |
| Domain Archaea | prokaryotic, single-celled organism that lack a nucleus in its cell and can live in EXTREME environments |
| Domain Eukarya | organisms with cells that contain a nucleus |
| Kingdom | a taxonmic rank 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 |
| heterotroph | an organism that CANNOT make its own food; known as a consumer in the food chain |
| asexual | a method of reproduction that requires 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 organisms are made up of 1 or more cells; tells are the basic unit of life and all cells come from other cells |
| Kingdom Archaebacteria | uincellular, asexual, auto and heterotroph, prokaryotic organism that live in extreme environments |
| Kingdom Eubacteria | uincellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate environments |
| Kingdom Protista | uni-and multi cellular sexual or asexual, auto- and heterotrophic eukaryotic organism that are microscpic |
| Kingdom Fungi | uni-and multi cellular sexual or asexual, auto- and heterotrophic eukaryotic organism; known as a decomposer in the food chain |
| Kingdom Plantae | multi cellular, sexual, and asexual, autotrophic, eukaryotic organism; known as a producer in the food chain |
| Kingdom Animilia | multi cellular, sexual, and asexual, heterotrophic, eukaryotic organism; known as a consumer in the food chain |
