Which of the following is not true of protists?
Malaria, red algae, green algae, and dinoflagellates are all examples of protists
Protists are diverse in part due to endosymbiosis, a process by which small, unicellular organisms are engulfed by larger unicellular organisms and eventually evolve to become organelles
A "protist" is broadly recognized as a eukaryote that is not an animal, fungus, or plant
All protists are unicellular by definition
