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 , 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 relationships |
Domain | the highest and largest rank of grouping organisms Three groups: Archaea , Bacteria , and Eurkarya |
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 , Archaea , and Eubacteria |
autotroph | an organism that is able to make its own food; known as a producer in 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 (a source) 100% DNA from 1 parent |
sexual reproduction | a method of reproduction that requires BOTH male and female parent 50% from 1 parent 50% from other parent |
cell theory | states that all living organisms one made up of 1 or more cells; cells are the basic unit of life and all cells come from other cells` |
Kingdom Archeabacteria | unicelluar , asexual , auto and heterotroph , prokaryotic organism that live in EXTREME environments |
Kingdom Eubacteria | unicelluar , asexual , auto and heterotroph , prokaryotic organism that live in moderate enviroments |
Kingdom Protista | uni – and multi cellular , sexual or asexual , heterotrophic , eukaryotic organism ; known as a decomposer in the food chain |
Kingdom Plantae | mulitcellular , sexual and asexual , autotrophs , eukaryotic organism ; known as a producer in the food chain |
Kingdom Animilia | multi cellular , sexual and asexual , heterotrophs , eukaryotic organisms ; known as consumer in food chain |
Kingdom Fungi | uni – and multi cellular sexual or asexual auto – and heterotroph , eukaryotic organism ; known as a decomposer in the food chain |
