A taxonomic kingdom comprised of protists, characterized by being eukaryotic and mostly single-celled
Kingdom Protista is one of the five biological kingdoms in the formerly used taxonomic classification of organisms (proposed by Robert Whittaker).
Protists are grouped into animal-like (protozoa), plant-like (single-celled and some multicellular, eukaryotic algae), and fungus-like (i.e. slime molds and water molds).
