Term | Definition |
---|---|
cell | the smallest unit of an organism that performs life functions |
nucleus | a structure found in Eukaryota cells that contain DNA and is responsible for controlling the activities of the cell. |
Eukaryote | a cell containing a membrane - enclosed organelles |
Proaryotic | 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: Archea, bacteria, and Eukarya. |
Domain Bacteria | Prokaryotic single-celled organism that lacks a nucleus in its cell. |
Domain Archea | prokayotic, single celled organism that lacks a nucleus in it's 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, Archea, and Eubacteria. |
heterotroph | an organism that CANNOT make it's own foo; known as a consumer in the food source. |
autotroph | an organism that is able to make it's own foo; known as a producer in food chain. |
asexual | a method of reproduction that requires only one parent. |
sexual | a method of reproduction that requires both male and female parent. |
cell theory | states that all living things are made up of 1 or more cell; 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 environment. |
kingdom Eubacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in extreme envirement |
Kingdom Eubacteria | unicellular, asexual, unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate environments |
Kingdom Protista | uni- and multicellular, asexual, auto and heterotrophic, eukaryotic organism that are microscopic |
Kingdom Fungi | uni- and multicellular, asexual or sexual, heterotrophic, eukaryotic organism; known as decomposers in the food chain |
Kingdom Plantae | multicellular, sexual and asexual, autotrophs, eukaryotic organism, known as the producer in the food chain. |
Kingdom Anamalia | multicellular, sexual and asexual, heterotrophs, eukaryotic organisms known as the consumer in the food chain. |
