Taxonomy
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; known as a consumer in the food chain |
asexual reproduction | a method of reproduction |
cell theory | states that all living organism are made up 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 live in extreme environments |
Kingdom Eubacteria | unicellular, asexual, auto and heterotrophic, prokaryotic organism that live in moderate enviroments |
Kingdom Protista | uni and multicellular sexual or asexual, auto and heterotrophic, eukaryoitic 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 Animila | multicellular, sexual and asexual, heterotrophs, eukaryotic organisms; known as a consumer in the food chain |
