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 nucles 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 | prokar yotic,single-celled organismthat 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,archaea,and eubacteria |
autotroph | an organism that is able to make it own food;known as a producer in the food chain |
heterotroph | an organism that cannot make it own food; know 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 |
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 cell |
Kingdom archeabacteria | unicellular,asexual,auto and heterotroph,prokaryotic organism that live in extreme environments |
kingdom eubacteria | unicellular,asexual,auto and heterotroph,prokaryotic organism |
kingdom protista | uni-and multi cellular sexual or asexual auto-and heterotrophic eukaryotic organism that are microscopic |
Kingdom Fungi | uni-and multi cellular sexual or asexual,hetero-trophic,eukaryotic organism;known as a decomposer in the food chain |
Kingdom plantae | multi cellular, sexual and a sexual,autotrophs,eukaryotic organism; know as a producer in the food chain |
Kingdom animilia | multi cellar,sexual and asexual,heterotrophs,eukaryotic organisms;know as a consumer in the food chain |
