What is protists? Protista. Definition. noun. A taxonomic kingdom comprised of protists, characterized by being eukaryotic and mostly single-celled. Supplement. Kingdom Protista is one of the five biological kingdoms in the formerly used taxonomic classification of organisms (proposed by Robert Whittaker). Protists are grouped into animal-like (protozoa), plant-like (single-celled and some multicellular, eukaryotic algae), and fungus-like (i.e. slime molds and water molds).

Antiprotozoal drug Protozoan, organism, usually single-celled and heterotrophic (using organic carbon as a source of energy), belonging to any of the major lineages of protists and, like most protists, typically microscopic. All protozoans are eukaryotes and therefore possess a “true,” or membrane-bound, nucleus.

Definitions &Translations The term protista was first used by Ernst Haeckel in 1866. Protists were traditionally subdivided into several groups based on similarities to the higher kingdoms: the unicellular animal-like protozoa, the plant-like protophyta (mostly unicellular algae), and the fungus-like slime molds and water molds.rotists were traditionally subdivided into several groups based on similarities to the higher kingdoms: the unicellular animal-like protozoa, the plant-like protophyta (mostly unicellular algae), and the fungus-like slime molds and water molds.

Protist The most popular contemporary definition is a phylogenetic one, that identifies a paraphyletic group: a protist is any eukaryote that is not an animal, (land) plant, or (true) fungus; this definition excludes many unicellular groups, like the Microsporidia (fungi), many Chytridiomycetes (fungi), and yeasts (fungi), and also a non-unicellular group included in Protista in the past, the Myxozoa (animal).

Biology for Kids Protists are organisms that are part of the biological kingdom called the protista. These organisms are not plants, animals, bacteria, or fungi.Protists are a very diverse group of organisms. They are basically all the organisms that don't fit into the other groups.ne major type of protist is algae. Algae are protists that perform photosynthesis. Algae are very similar to plants. They have chlorophyll and produce food using oxygen and the energy from the Sun. However, they are not considered plants because they do have specialized organs or tissues.

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

Protist Some protists, sometimes called ambiregnal protists, have been considered to be both protozoa and algae or fungi (e.g., slime molds and flagellated algae), and names for these have been published under either or both of the ICN and the ICZN.ther protists include pathogenic species such as the kinetoplastid Trypanosoma brucei, which causes sleeping sickness and species of the apicomplexan Plasmodium which cause malaria.

Protist Protist, any member of a group of diverse eukaryotic, predominantly unicellular microscopic organisms. They may share certain morphological and physiological characteristics with animals or plants or both. The term protist typically is used in reference to a eukaryote that is not a true animal, plant, or fungus or in reference to a eukaryote that lacks a multicellular stage.

- Protists are microscopic unicellular organisms that don't fit into the other kingdoms. Some protists are considered plant-like while others are considered animal-like. The amoeba is considered an animal-like protist (protozoan) because it moves and consumes its food. Protozoans are classified by how they move, some have cilia or flagella, but the amoeba has an unusual way of creeping along by stretching its cytoplasm into fingerlike extensions called pseudopodia.
