Which are the groups of living beings that form the protist kingdom?
The protist kingdom includes protozoans and algae. (Two groups of fungi with similar characteristics to protozoans, myxomycetes and oomycetes, have been classified as protists.) Unicellular protozoans and algae are unicellular eukaryotes. The pluricellular algae are eukaryotes of simple structure too. It is believed that protists are phylogenetic ancestors of living beings of the other eukariotic kingdoms (fungi, animals and plants).
