1. Chapter 28 Key Points

2.  Simplest Eukaryotes  Most diverse kingdom  Can be unicellular or multicellular  Paraphyletic  Under reorganization

3.  Evolved from cyanobacteria  Serial endosymbiosis  Evidence: ▪ Separate DNA ▪ Multiple membranes ▪ Similar reproduction

5.  Animal-like Protists  Ex: ciliates, euglenids, diplomonads  Plant-like Protists  Ex: algae  Fungus-like Protists  Ex: slime molds, water molds

6.  Heterotrophs  Mobile  Often cause disease  Sleeping sickness  Malaria  Chagas disease  Dysentery

9.  Autotrophs  Include largest protists (kelp)  Closest relatives of land plants  Used in food processing  Can cause “red tide”

11.  Some produce fruiting bodies like fungi  Model for evolution of multicellularity  Often act as decomposers
