LESSON 5: KINGDOM PROTISTA
Background Information
The most ancient of the eukaryotic life forms and a very diverse group of microorganisms. They include a variety of single-celled organisms and those that form colonial multi-cellular organism that do not show differentiation into tissues. Beside their relatively simple levels of organization, protists do not have much in common. It is this simple cellular organization that is what distinguishes the protists from other eukaryotes such as fungi, animals, and plants. Thus they can perhaps be best described as eukaryotes that are not fungi, animals, or plants.
For their nutritional requirements they can be: heterotropic, autotrophic, or both.
Their reproduction is also diverse as some reproduce sexually while other reproduce asexually
Many protists are significant pathogens of both animals and plants. Examples include Plasmodium falciparum which causes malaria in humans and Phytophthora infestans which causes late blight in potatoes.
Examples: Slime molds, algae, paramecium, amoeba
