Most of the protozoa species have flagellum, cilia and pseudopodia. Sporozoa, which do not have any locomotory structure, comprises subpellicular microtubules, which help in their slow movement.

Protozoa are unicellular, eukaryotic, heterotrophic organisms. They are free-living or parasites and are around sixty to seventy thousand protozoans categorised into different groups. These species lack a cell wall, and it comprises the mouth, intestinal tract, anus, and many other cell organelles that perform various functions.
