Chapter 25: The Origin and Diversification of Eukaryotes Overview: Shape Changers Because eukaryotes have internal membranes, they can perform a wide variety of tasks that prokaryotes are unable to perform. An example is a Didinium eating a larger Paramecium The cytoskeleton allows the Didinium to change its shape enough to engulf the Paramecium Concept 25.1 Eukaryotes arose by endosymbiosis more than 1.8 billion years ago Endosymbiosis in Eukaryotic Evolution There is now considerable evidence that much protist diversity has its origins in endosymbiosis Endosymbiosis is the process in which a unicellular organism engulfs another cell, which becomes an endosymbiont and then organelle in the host cell Mitochondria evolved by endosymbiosis of an aerobic prokaryote

INSTRUCTIONS: When submitting your protist resume, just insert your response in the areas where the text is blue. Please contact me if you are confused with creating your protist resume. (Scientific name of protist) (Phylum of your protist) (Common ecosystem of your protist) Objective (describe what your protist does and where your protist normally performs this function) Background (Characteristics) (describe the shape of your protist) (how does your protist move) (how does your protist obtain food) Work Experience (3 Contributions your protist provides to the environment or to other organisms) (contribution #1) (contribution #2) (contribution #3) References (identify 3 organisms that belong in the same phylum as your protist) (organism #1 ? where can they be found?)

Chapter 28- Protists Overview: Living Small Protist- the informal name of the group of mostly unicellular eukaryotes Protists constitute a polyphyletic group, and Protista is no longer valid as a kingdom caused by systematics. Molecular data shows there is genetic diversity. Concept 28.1: Most eukaryotes are single celled organisms Protists are eukaryotes most are unicellular, but there are some colonial and multicellular species Protists are the most diverse of the eukaryotes Single celled protists can be very complex, as all biological functions are carried out by organelles in each individual cell don?t see the division of labor like in multicellular eukaryotes, every single cell has all the organelles a protist needs to survive
