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...
Red Tide
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.
Metazoa– Organisms that have organized tissues, unlike the protozoa.Protist– A name that reflects the addition of photosynthetic organisms into the unrelated group of protozoa.1. A scientist is watching an unknown organism develop. As the cells divide, they begin to form distinct tissue layers. Which of these describes the organism? A. Protozoa B. Metazoa C.Ciliate 2. An organism under the microscope is seen to be free-swimming, single-celled, and covered in tiny hairs, that move about. What phylum does this protozoa bel...
Protozoa (sg.: protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris.
Category:Protozoan. From Wikimedia Commons, the free media repository. English: Protozoa (from the Greek words πρωτό, proto, meaning first, and ζωα, zoa, meaning animals; singular protozoon or also protozoan) are a diverse group of single-cell eukaryotic organisms, many of which are motile.
This diverse group of organisms vary in shape, size and features. View this extensive image gallery of protozoan taken using different imaging techniques including scanning electronic micrographs, transmission electron micrograph and light micrographs.
