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 a cell that contains 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 the foo 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 100% DNA from one parent......(CLONE) |
sexual reproduction | a method of reproduction that requires both male and female parent 50% from one parent 50% from one 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 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 multi cellular sexual or asexual auto- and heterotrophic eukaryotic organism that are microscopic |
Kingdom Fungi | uni-and multi cellular sexual or asexual, heterotrophic,eukaryotic organism;known as a decomposer on the food chain |
Kingdom Plantae | multicellular,sexual and asexual,autotrophs,eukaryotic organism;known as a producer in the food chain |
Kingdom Animilia | multicellular,sexual and asexual,heterotrophs,eukaryotic organism;known as a consumer in the food chain |
