<h3>What is Protozoa?</h3>

Protozoa is a group of single celled, non- prokaryotic organisms.

These are heterotrophs and reproduce asexually by binary fission.
The Protozoa consists of many unrelated or loosely related organisms.
They are divided into four major groups: Sarcodina, Flagellates, Ciliates and Sporozoans..
Some protozoa consist of two phases in their life cycle: proliferative stage (trophozoites) and resting stage (cysts).
Trophozoites consists of the proliferative stage in which the protozoa divides and reproduces.
The resting cyst form helps the protozoa to survive harsh environmental conditions like harmful chemicals, extreme temperature and nutrient and water deficiency.
