It can now be digested for its biomolecules to support growth and cell division. Then, at a vantage point, they engulf the whole particle, eventually covering it entirely and forming its storage vacuole within the cell. They first sense the organic particle that is targeted using special receptors in their cell membrane.

Most protozoan ingests particulate materials by phagocytosis or “cell eating,” which is the process of engulfing and digesting microscopic organic particles by surrounding it with a portion of their cell membrane. Phagocytosis and pinocytosis are the two kinds of endocytosis. Since they are heterotrophs, they obtain their food by endocytosis, which is a process wherein a particle is taken into their cell.

It can come either from other protozoa, bacteria, animals, or even just environmentally available substrates, as their primary nutritive sources. What and How do Protozoa Eat?Ĭan these microscopic creatures efficiently obtain their food? Does their diet need to be smaller than them, or can they slowly devour a larger organism? Can they eat more advanced animals? Surprisingly, the answer to all of these questions is yes!Īs mentioned earlier, most protozoa are heterotrophic and require organic compounds from other exogenous sources. The tissues that are adequate habitats for protozoal life include the human gut, liver, and red blood cells. The human body is an ideal habitat for some of these parasitic organisms since the human physiologic temperature and pH are regulated, and the vicinity of the human tissue is adequately nourished, making it a suitable home for these microorganisms. Some of these parasitic protozoans call for transmission through different hosts from snails, fishes, insects, and birds until they reach their desired host, usually a large mammal. Meanwhile, parasitic protozoan resides in their respective host in different parts of the animal body. While some choose safer environments for sustaining life, others take on a great challenge and can thrive in extremely harsh environments ranging from the piping hot temperatures of the desert, up to the frigid temperatures of the arctic.īesides some offbeat habitats, they can also be present in aerial habitats such as surfaces of trees or as ‘cyst’ in the air. Some protozoa are observed growing in soil, sewage, and sludge being adept at living in the ground with its adequate warmth, richness in organic materials for food, and a consistent supply of moisture from the water vapor in the air. Protozoa use their whip-like projections called flagella, hair-like structures called cilia, and false feet known as pseudopods to propel and push themselves through whatever medium they find themselves in.

Their property of motility, which is the capacity to move at free will, allows it to navigate towards food, light, warmth, and other desired environments. The term protozoa came from two Greek words proto – “ first” and zoa – “ animals.” Protozoa are not considered animals as most people conceive, instead, they are so-called because of their animal-like behavior from movement to feeding and many more things in between. In this article we will look at the definition, habitat, reproduction, evolution and much more of protozoa. Some of these protozoans that you come into contact with are completely harmless in terms of human health, but other can cause nasty illnesses. The odds are, you will probably have one species of protozoa in your body throughout your life. There are about 50,000 identified species in the protozoa subkingdom and some of the most identifiable microorganisms under this classification are paramecium, Amoeba, Giardia, Blepharisma, and Stentor. Protozoa is taxonomic designation that is used to classify a set of eukaryotic, single-celled, microorganisms into the rank of subkingdom.
