| Term | Definition |
|---|---|
| cell | the smallest unit of an organism that performs 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 membrane-enclosed nucleus and organelles |
| unicellular | an organism made up one single sell |
| multicellular | an organism that is made up of more than on 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 organisms that lacks a nucleus in its cell |
| Domain Archaea | Prokaryotic, singled-celled organism that lacks a nucleus in its cell and can live in extreme enviroments |
| Domain 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; 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 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, prokayotic organism that live in extreme enviroments |
| Kingdom Eubacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate enviroments |
| Kingdom Protista | uni – multicellular sexual or asexual auto and heterotrophic eukaryotic organism that are microscopic |
| Kingdom Fungi | uni – and multicellular sexual or asexual, heterotrophic, eukaryotic organism; known as a decomposer 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, heterotrophs, eukaryotic organisms; known as a consumer in the food chain |
