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 environment |
domain eukarya |
organism with cells that contain a nucleus |
kingdom |
a taxonomic rank below domain 6: animalia,fungi , plantae, protista , archaea, and eubacteria |

an organism that is able to make its own food;known as a producer in food chain |
heterotroph |
an organism that CANNOT make it its own food ; known as a consumer in the food chain |

cell theory |
state that all living organisms are made up of 1 or more cells; cells are basic unit of life and all cell come from other cells |
