Protozoa are a diverse group of single-celled organisms that are classified as animals. They are heterotrophic, meaning that they rely on other organisms for their energy and nutrients. Protozoa are found in a variety of environments, including freshwater, marine, and terrestrial ecosystems.
Protozoa are classified into several different groups based on their characteristics and behaviors. Some common groups of protozoa include:
Amoebae: Amoebae are single-celled organisms that move by extending pseudopodia, or temporary extensions of their cell membrane. They are found in a variety of environments, including freshwater, soil, and the human intestine.
Flagellates: Flagellates are single-celled organisms that move using one or more whip-like appendages called flagella. They are found in a variety of environments, including freshwater, marine, and soil.
Ciliates: Ciliates are single-celled organisms that move using numerous tiny hair-like appendages called cilia. They are found in a variety of environments, including freshwater, marine, and soil.
Apicomplexans: Apicomplexans are single-celled parasites that are known for their complex life cycles. They are found in a variety of hosts, including humans, animals, and plants.
Protozoa are important because they are a major component of many ecosystems, serving as decomposers, herbivores, and predators. They are also important in human health, as some species are parasites that can cause illness in humans and animals.

What is Protozoa? Protozoa Definition Protozoa are a diverse group of single-celled eukaryotic organisms that can be either free-living or parasitic. They primarily feed on organic matter, including microorganisms and organic debris. Protozoa are characterized by their lack of a rigid cell wall, motility, and heterotrophic feeding habits. Examples include Amoeba, Paramecium, Euglena, and Trypanosoma. … Read more

What is Entamoeba Histolytica? Definition of Entamoeba Histolytica Entamoeba histolytica is a single-celled, anaerobic parasitic organism that causes amoebiasis, a disease characterized by intestinal and sometimes extraintestinal infections. It exists in both active (trophozoite) and dormant (cyst) forms, the latter being responsible for environmental survival and transmission of the infection, particularly in tropical regions. The … Read more

Fascioliasis is an infectious disease caused by Fasciola parasites, which are flatworms referred to as liver flukes. The adult (mature) flukes are found in the bile ducts and liver of infected people and animals, such as sheep and cattle. In general, fascioliasis is more common in livestock and other animals than in people.
