II. These are also called as animal protists. Essentially, protozoa are single-celled eukaryotes.This means that they are single celled organisms that have a nuclei as well asa number of other important organelles within the cytoplasmand enclosed by amembrane. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. Its subgroups are the diplomonads, parabasalids, and euglenozoans. The protozoa are then placed into various groups primarily on the basis of how they move. Introduction and Classification of Parasites is an very important and basic topic of Parasitology.
