There is no single feature such as evolutionary history or morphology common to all these organisms and they are unofficially placed under a separate kingdom called Protista.

Feb 2, 2023 · Protists are the oldest eukaryotic microorganisms, having a nucleus and other membrane-bound organelles. Since they do not wholly fit into other groups like plants, animals, bacteria, or fungi, they are categorized under a separate kingdom called Protista.

Aug 25, 2023 · Protist (biology definition): Any of a group of eukaryotic organisms belonging to the Kingdom Protista. Protists include: (1) protozoa, the animal-like protists, (2) algae, the plant-like protists, and (3) slime molds and water molds, the fungus-like protists.

Protist parasites include the causative agents of malaria, African sleeping sickness, and waterborne gastroenteritis in humans. Other protist pathogens prey on plants, effecting massive destruction of food crops.

Protists are simple eukaryotic organisms that are neither plants nor animals or fungi. Protists are unicellular in nature but can also be found as a colony of cells. Most protists live in water, damp terrestrial environments or even as parasites. The term ‘Protista’ is derived from the Greek word “protistos”, meaning “ the very first “.
