Term | Definition |
cell | the smallest unit of an organism that performs life functions |
nucleus | a structure found in eukaryotic cell 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 structures function and relationship |
Domain | the highest and largest rank of grouping organisms three group; arch, bacteria, and eukarya |
bacteria | porkaryotic, single-celled organisms that lack a nucleus in its cell |
Archaea | prokaryotic single-celled organisms that that lack a nucleus in its cell and can live in extreme environments |
Eukarya | organisms with cells that contain a nucleus |
Kingdom | a tax rank below Domain 6 groups: animalia, fungi, plantea, protista, archaed, and eulbacteria |
autotroph | an organism that is able to make its own food; known as a producer in a food chain |
heterotroph | an organism that can not make its own food :known as a consumer in a food chain |
asexual | a method of reproduction that requires only one parent 100% DNA from one parent |
sexual | a method of reproduction that requires both male and female parent 50% from one parent 50% from one parent |
cell theory | stats that all living organisms are made up of one or more cells; cells are the basic unit of life and all cells come from other cells |
Arceabacteria | unicellular, asexual, auto and heterotroph, prokaryotic organisms that live in extreme environment |
Eubacteria | unicellular, asexual, auto and heterotroph, prokaryotic organisms that live in moderate environments |
protista | uni-multicellular sexual or asexual auto- and heterotrophic eukaryotic organisms that are microscopic |
Fungi | uni- and multicellular sexual or asexual, heterotrophic, eukaryotic organisms; known as a decomposer in the food chain |
Plantae | multicellular, sexual and asexual, autotrophs, eukaryotic organisms known; as a producer in the food chain |
Animilia | multicellular, sexual and asexual, heterotrophs, eukaryotic organisms; also known as a consumer in a food chain |
