Protists may be unicellular or multicellular. They vary in how they get their nutrition, morphology, method of locomotion, and mode of reproduction. Important structures of protists include contractile vacuoles, cilia, flagella, pellicles, and pseudopodia; some lack organelles such as mitochondria. Taxonomy of protists is changing rapidly as relationships are reassessed using newer techniques.

It highlights model organisms like Arabidopsis thaliana and Drosophila melanogaster, and includes a discussion on bacteria, archaea, and viruses. Notable pathogens like E. coli and anthrax are addressed, along with the rapid identification of microorganisms and the importance of viruses such as influenza and smallpox.

In the very recent past--and still in many textbooks today--eukaryotic organisms were lumped into four groups: Animals, Plants, Fungi, and Protists. Organisms were classified as belonging to Kingdom Protista by saying "Well, it isn't an animal, plant, or fungus," so it isn't surprising to find out that these organisms are not actually genetically related to each other.

Are all organisms known as "protists" singled-celled organisms? If you were shown an algal species that produced large amounts of carotenoids, what would you infer about the ecology of this organism? What regions of the spectrum of light do chlorophylls absorb? What are the current supergroups within Domain Eukarya, and why are they grouped the way they are?
