What is a Protozoa?

A Protozoa is indeed a single-celled organism that can commonly be found in untreated water sources. Protozoa are characterized by their simplicity, being made up of only one cell, which allows them to carry out all essential life processes independently. They can exist in various environments, particularly in water, where they may thrive in conditions that are less than sanitary. This ability to survive in various environments, including the human body, makes them significant in both ecological systems and health-related contexts.

Protozoa encompass a wide range of species, some of which are free-living, while others can be parasitic, affecting humans and animals. Understanding their nature is crucial in fields like microbiology and environmental science, as they can impact water quality and health outcomes.
