What do ciliates use to move (locomotion)? Eukaryotic cells, the unifying feature of protists, are common to complex multi-cellular organisms belonging to the three eukaryotic kingdoms (Fungi, Plantae and Animalia) but clearly differentiate protists from members of the prokaryotic kingdom (Monera).
