As the catchall term for eukaryotic organisms that are not animal plant or fungi it is not surprising that very few characteristics are common to all protists.

The __________ protists are all unicellular heterotrophs knowns as protozoans. Examples of heterotrophic protists include amoebas paramecia sporozoans water molds and slime molds. In some classification systems any organism belonging to the kingdom Protista originally including bacteria protozoans algae and fungi regarded as distinct from plants and animals.
