WebMany of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove “excavated” from one side. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. Its subgroups are the diplomonads, parabasalids, and euglenozoans. Most protists are extremely small microorganisms. They are mostly single-celled organisms and can have cells as small as prokaryotic cells between 0.5-2 µm A key feature of all protists are their eukaryotic cells.
