MOnerans and protistan

1. Currently, all living organisms are classified into three domains:

« Eukarya — eukaryotic organisms that contain a membrane-bound nucleus (includes protist, plants, fungi and animals)
« Archaea — prokaryotic cells lacking a nucleus and consist of the extremophiles (e.g. methanogens, thermophiles, etc.)
+ Eubacteria — prokaryotic cells lacking a nucleus and consist of the common pathogenic forms (e.g. E. coli, S. aureus, etc.)
