Protists are one-celled organisms. Symbiotic protists are protists that live with other larger organisms in a mutually beneficial relationship. The anaerobic parabasalid species of protist is an example. Photosynthetic protists are the protists that process sunlight. The dinoflagellates Noctiluca and Pyrocystis are examples of this type of protist. There are also protists that serve both purposes: they are both symbiotic and photosynthetic. The protists zooxanthellae are an example of this type of protist.
A protist is any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates. In some systems of biological classification, such as the popular five-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of organisms which are unicellular or unicellular-colonial and which form no tissues. Besides their relatively
