Stanford-science unit 11
| 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 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 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 lacks a nucleus in its cell |
| 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,archea,and eubacteria |
| autotroph | an organism that is able to make its own food;known as a producer 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 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 archea bacteria | unicellular,asexual,auto and heterotroph,prokaryotic organism that live in extreme enviroments |
| kingdom eubacteria | unicellular,asexual,auto and heterotroph,prokaryotic organism that live in moderate enviroments |
| kingdom protista | uni and multi cellular sexual or a sexual auto and hetrotrophic eukaryotic organism that are microscopic |
| kingdom fungi | uni and multi cellular sexual or a sexual hetrotrophic,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,eukaryotic organism;known as a consumer in the food chain |
