Protozoans are simple organisms, or living things. They belong to a group of organisms called protists, which are neither plants nor animals. Most protozoans are so tiny that they can be seen only with a microscope. Amoebas and paramecia are types of protozoan.

Oct 16, 2023 · Protozoa are small (but not simple) organisms. They are single-celled heterotrophic eukaryotes, which eat bacteria and other food sources. It is an old term, and the wider term protist is generally preferred today. However, 'protozoa' is often used for convenience, especially in junior education.

Major Types. Ciliated protozoans, or ciliates, are characterized by a covering of short, hairlike structures called cilia. The cilia move in wavelike patterns and are used like oars to propel the organisms and to help direct food particles into their mouths. Ciliates have cell membranes.

Organisms known as protozoa include a wide range of organisms, most of which are free-living single-celled eukaryotes. Therefore, protozoa fit into the Domain Eukarya. Although the different phyla of the kingdom Protista are not closely related, they are nonetheless classified together because of their large differences from the other kingdoms of p...
Malaria
Malaria is a disease that effects hundreds of millions of people worldwide, every year. It is estimated that malaria kills three million people a year, half of which are young children. Malaria is caused by several protozoa in the genus Plasmodium. This particular protozoa carries out life cycles in both the digestive systems of mosquitos, and in human blood cells. The unicellular protozoans enter the bloodstream of humans during a mosquito bite. They find an uninfected red blood cell, and us...

An interesting phenomena in the ocean is also caused by another phylum of protozoa. The Dinoflagellates are a group of protozoa that exist mainly as free-swimming unicellular organisms, while other exist symbiotically within certain invertebrates. Groups of dinoflagellates that are free swimming can undergo drastic periods of reproduction, known as blooms. If a bloom produces enough dinoflagellates, the ocean water will become pink or even red because of their density. Unfortunately for any o...
There are many phyla in the Domain Protista. While this represents a wide variety of them, it is not close to all of them. Part of the reason there is so much diversity in this domain is that the phyla are not closely related.
