The Five Kingdom system (first proposed in 1969 and now the most widely used) places all prokaryotes (organisms without nuclear membranes) in a single Kingdom Monera, and separates the three principal branches of multicellular eukaryotes as separate Kingdoms. In this sytem, Protista tends to remain as a catch-all taxon for eukaryotic groups, such as the highly diverse algae, that do not fit readily into the other Kingdoms.
