Origins and Evolution of Eukaryotic Microbes Eukaryotic cells evolved through endosymbiotic events: mitochondria originated from α-proteobacteria, and chloroplasts from cyanobacteria. Some eukaryotes later acquired plastids through secondary endosymbiosis ...

Protists, Endosymbiosis, and Eukaryotic Diversity — Unraveling Microbial Evolution and Adaptation | Chapter 28 of Campbell Biology Welcome to Last Minute Lecture! In this comprehensive summary of Chapter 28 from Campbell Biology , we dive into the world of protists—an extraordinary group of eukaryotes at the root of life’s complexity. This chapter unpacks how protists evolved, their ecological impact, and the astonishing diversity found within the eukaryotic domain.

Protists are a catch-all group of eukaryotic organisms that are not classified as plants, animals, or fungi. They can be unicellular, colonial, or multicellular, and thrive in aquatic, terrestrial, and even extreme environments. The majority of eukaryotic diversity can be found among protists, making them critical to understanding the evoluti...
