What is a Protist?. Protists. are eukaryotes (organisms whose cells have a nucleus). that cannot be classified as plants, animals, or fungi.. Additionally, all protists live in moist surroundings.. Vocabulary. Medical parasitology:. “the study and medical implications of parasites that infect humans”. Eukaryote:. a cell with a well-defined chromosome in a membrane-bound nucleus.

They are so small that you need a microscope to see them. . Viruses, bacteria and fungus are all types of micro-organism. Micro-organisms that cause diseases are often called germs. . Parasites.
