Motility and digestion
Tulodens are 2 of the slow-moving form of protozoa . They move around with whip-like tails called flagella, hair-like structures called cilia, or foot-like structures called pseudopodia. Others do not move at all. Protozoa may absorb food via their cell membranes, amoebas, surround food and engulf it, and yet others have openings or "mouth pores". All protozoa digest their food in compartments called vacuoles.
Protozoa are an important food source for microinvertebrates. As predators, they prey upon unicellular or filamentous algae, bacteria, and microfungi. Protozoa are consumers, both herbivoresand carnivores. They also control bacteria population.
Protozoa can reproduce by binary fission or multiple fission. Some protozoa reproduce sexually, some asexually. An individual protozoan is hermaphrodite.
They are classificated into ciliates, mastigophorans, and apicomplexans. Most protozoa can move about on their own.
Some protozoa are human parasites, causing diseases. Examples of human diseases caused by protozoa:
