Answer» ong>Answer: Protozoa (also protozoan, plural protozoans) is an INFORMAL term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Historically, protozoans were regarded as "one-celled animals", because they often POSSESS animal-like behaviours, such as motility and predation, and LACK a cell wall, as FOUND in plants and many algae. ALTHOUGH the traditional practice of grouping protozoa with animals is no longer considered valid, the term continues to be used in a loose way to describe single-celled protists (that is, eukaryotes that aren't animals, plants, or fungi) that feed by heterotrophy.
