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 1 single cell |
multicellular | an organism made up of more than 1 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,Eukarya |
Domain Bacteria | prokarotic single-celled organism that lacks a nucleus in it's cell |
Domain Archaea | prokarotic single-celled organism that lacks a nucleus in it's cell and can live in EXTREME enviorments |
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 can make it's own food |
heterotroph | an organism that CANNOT make it's own food it is a consumer in the food chain |
asexual | reproduction that needs only 1 parent |
sexual | reproduction that needs 2 parents |
cell theory | states that all living organisms are made 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 can live in EXTREME enviroments |
kingdom Eubacteria | unicellular asexual auto heterotroph prokaryotic organism that live in moderate enviroments |
kingdom Protista | uni and multicelluler sexual or asexual auto and heterotroph eukaryotic organism that are mircoscophic |
kingdom Fungi | uni and multicellular sexual or asexual heterotroph eukaryoticorganism that is a decomposer in the food chain |
kingdom Plantae | multicellular sexual or asexual autotrophs eukaryotic organismthat is a producer in the food chain |
kingdom Animilia | multicellular sexual and asexual heterotrophs eukaryotic organisms that is a consumer in the food chain |
