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 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 environments |
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; |
asexual reproduction | a method of reproduction that requires only one parent 100% DNA from 1 parent |
sexual reproduction | a method of reproduction that requires that 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 cells come from other cells |
Kingdom Archeabacteria | unicellular,asexual,auto and heterotroph,prokaryotic organism that live in extreme environments |
Kingdom Eubacteria | unicellular,asexual,auto and heterotroph,prokaryotic organism that live in moderate environments |
Kingdom Protista | uni- and multicellular sexual or asexual auto- and heterotrophic eukaryotic organism that are microscopic |
Kingdom Fungi | uni- and multicellular sexual or asexual,heterotrophic , 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 Animalia | multicellular,sexual and asexual,heterotrophs , eukaryotic organisms;known as a consumer in the food chain |
