| 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, 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 classified organisms by their structure, function and relationships |
| domain | the highest and largest rank of grouping organisms three groups:Archea Bacteria, and Eukarya |
| domain bacteria | proaryotic, 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 Eurkary | organism with cells that contain a nucleus |
| kingdom | a taxonmic rank below domain 6 groups:animals, fungi, plantea, protista, archea 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 one parent |
| sexual reproduction | a method of reproduction that requires both male and female parent 50% from 1 parent 50% from one 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 hetertroph, prokaryotic organism that live in moderate enviroment |
| kingdom Eubacteria | unicellular, asexual, auto and heterotrophic, prokaryotic organism that live in a moderate enviroments |
| kingdom Protista | uni- and multicellular sexual or a sexual auto - and heterotrphic eukaryotic organism that are microscopic |
| kingdoom Fungi | uni- and multicellular sexual or asexual, autotrophs, eukarotic 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 |
| king Animilia | multicellular , sexual and asexual and heterotrophs, eukaryotic organisms;known as a consumer in the food chain |
