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
