What are the class of protozoa?

CLASSES OF PROTOZOA The protozoa are contained within the kingdom Protista along with the unicellular algae. The classes of protozoa are categorized by a variety of factors: cell architecture, motility structure, even hosts. They do not photosynthesize, rather being chemoheterotrophic like animals.

What is protozoa and its characteristics?

Protozoa are eukaryotic microorganisms. Although they are often studied in zoology courses, they are considered part of the microbial world because they are unicellular and microscopic. Protozoa are notable for their ability to move independently, a characteristic found in the majority of species.
