| 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 |
|
Prokaryotic |
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 |
| classification | the process of grouping things based on similarities |
| taxsonomy | 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 and can live in extreme environments |
| Domain Archaea | prokaryotic, single celled organism that lacks a nucleus in its cell and can live in extreme enviroments |
| Domain Eukarya | organisms 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 yhe 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 enviroments |
| Kingdom Euibacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate enviroments |
| Kingdom Protista | uni – and multi cellular 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 and asexual, heterotrophs, eujkaryotic organisms; known as a consumer in the food chain |
