The Kingdom Protista consists of Eukaryotic organisms that do not belong to the Plant, Animal or Fungus Kingdoms. Most of the organisms (also called protists) in the Protista Kingdom are unicellular, though some are multicellular.

Characteristic FeaturesEdit

  • Cells are Eukaryotic
  • Autotrophic and Heterotrophic
  • Organisms display characteristics of Kingdom Animalia, Plantae and Fungi

Further ClassificationEdit

This list is very brief and does not go into detail regarding the various classes and beyond.

  • Sub-Kingdom: Protozoa
    • Unicellular microorganisms such as amoebas (Animal-like)
  • Sub-Kingdom: Algae
    • Mostly photoautotrophic and aquatic organisms (Plant-like)
    • Have a Cellulose Wall
    • Reproduce sexually or asexually
  • Sub-Kingdom: Mold
    • Have a cellulose based cell wall with no chitin (Fungus-like)
    • Reproduce sexually in water


  • Under Carl Linneus's Two Kingdom Classification, Protozoa were placed under a Phylum of Animalia. This was rectified under the 5 Kingdom Classification by Robert Whittaker.
