multicellular | an organism made up of more than one cell and often made up of different types of cell |
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 Archaea | 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 enviorments |
domain Eukarya | organisms with cells that contain a nucleus |
kingdom | a taxonomic rank below Domain 6 groups :Animalia,Fungi,Plantae,Protista,Archaea,and Eubacteria |
