  1. Kingdom: Protista Protists are a diverse group of eukaryotic microorganisms. They do not have much in common except that they are relatively simple eukaryotes. They are either unicellular or multicellular without reaching the specialized tissue level of organization. Protists include organisms such as algae, amoebae, protozoans, euglena, and slime molds. Protists live in almost any environment that contains liquid water. Some protists, such as algae, are photosynthetic, so they are autotrophs. Other protists are heterotrophs, obtaining nutrients from their environment. Amoebae engulf, or take into their membrane, other cells. This process is called phagocytosis. Most protists reproduce asexually, through a form of cell division. Other protists engage in a form of sexual reproduction. Some protists are responsible for diseases such as malaria in humans and potato blight in potato plants. Research scientists are experimenting with ways to use protists to wipe out fire ants and other pests.
