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 organelles |
prokaryotic | a cell lacking nucleus or any other membrane - enclosed organelles |
unicelluar | an organism made up of one single cell |
multicelluar | an organism made up of more than one cell, and often made up of different types of cells |
classification | the process 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 |
Domain Bacteria | prokaryotic single- celled organism that lacks nucleus in its cell |
Domain Archaea | prokaryotic, single - celled organism that lacks 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, 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 food chain |
asexual reproduction | a method of reproduction that requires only one parent 100% DNA from one parent |
sexual reproduction | a method of reproduction that requires both male and female parent 50% of DNA from each parent |
cell theory | states that all living organisms 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 heteortroph, prokaryotic organism that live in extreme enviroments |
Kingdom Protista | uni- and multicelluar sexual or asexual auto- and heterotrphic eukaryotic organism that are microscopic |
Kingdom Eubacteria | unicelluar, asexual auto and heterotroph prokaryotic organism that live in moderate enviorments |
Kingdom Fungi | uni- and unicelluar sexdual or asexual auto- and heterotrophic, eukaryotic organism; known as a decomposer in the food chain |
Kingdom Plantae | multicelluar, sexual and asexual, autotrophs, eukaryotic organism; known as a producer in the food chain |
Kindom Animilia | multicelluar, sexual and asexual, heterotropohs eukaryotic organisms; known as a consumer in the food chain |
