Detailed explanation-1: -Protozoa are microscopic unicellular eukaryotes that have a relatively complex internal structure and carry out complex metabolic activities. Some protozoa have structures for propulsion or other types of movement.
Detailed explanation-2: -The protozoa are bigger than bacteria and contain a definite nucleus and other membrane bound organelles. They are unicellular eukaryotes so it is more like plants and animals. The main feature of protozoa is they can move and eat other small microorganisms.
Detailed explanation-3: -Historically, protozoans were regarded as “one-celled animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae.
Detailed explanation-4: -Protozoa are single celled organisms. They come in many different shapes and sizes ranging from an Amoeba which can change its shape to Paramecium with its fixed shape and complex structure. They live in a wide variety of moist habitats including fresh water, marine environments and the soil.
