---|---|
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 |
Eukarotic | a cell containing a membrane-enclosed nucleus and organelles |
Prokaryotic | a cell lacking a nucleus or any membrane- enclosed organelles |
unicellular | an organism made up of one single cell |
multicellular | an organism made up of one single cell |
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 |
(Domain) Bacteria | Prokaryotic, single celled organism that lacks a nucleus in it's cell |
(Domain) Archaea | Prokaryotic, single celled organism that lacks a nucleus in it's call and can live in extreme environments |
(Domain) Eukarya | organisms with cells that contain a nucleus |
Kingdom | taxonomic rank below Domain |
autotroph | an organism that is able to makeT make it's owm food; known as a producer in the food chain |
heterotroph | an organism that CAN NOT make it's owm food; known as a consumer in the food chain |
