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 |
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 |
Eukaryotic | a cell containing a membrane-enclosed nucleus and organelles |
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 environment |
Domain Eukarya | organisms with cells that contain a nucleus |
Kingdom | a taxonomy rank below Domain 6 groups : Animalia, Fungi, Plantae, Protista, Archea, and Eubacteria |
autotroph | an organism that is able to make it's own food; known as a producer in food chain |
heterotroph | an organism that CANNOT make it's own food; known as a consumer in the food chain |
asexual reproduction | a method of reproduction that requires only one parent 100% DNA from 1 parent |
sexual reproduction | a method of reproduction that requires both male and female parent 50% from 1 parent 50% from another 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 enviroments |
Kingdom Eubacteria | unicellular, asexual, auto and heterotroph, prokaryotic organism that live in moderate enviroments |
Kingdom Protista | uni- and multicellular sexual or asexual 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 autotrophis eukaryotic organism; known as a producer in the food chain |
Kingdom Animilia | multicellular sexual and asexual heterotrophs, eukaryotic organisms; know as a consumer in the food chain |
