What two kingdoms are used to classify bacteria?

There are two kingdoms of bacteria namely Monera & Protists.Normally Protists is a link between the Monera's & Fungi,Animalia & Plantae .Monera's are the unicellular prokaryotic organisms bacterias, having one single cell.Protists are the multicellular bacterias having many cells.Scientists can easily classify them broadly into two separately.

The organisms in the kingdom Monera are unicellular or filamentous. THE CELLS ARE WITHOUT MEMBRANE-BOUND CELL Organelles are either motile or non motile,they exhibit autotrophic,heterotrophic,parasitic or saprophytic mode of nutrition.Reproduction is either asexual or with the help of fission or budding.

eg.archaebacteria,eubacteria,cyanobacteria,actinomycetes,etc.
