Chapter 35 protists

Eukaryata

• Endosymbiosis mitochondria, chloroplasts, centrioles evolved from aerobic bacteria
• Supporting evidence
• Mitochondrial and chloroplast DNA
• M&C ribosomes
• Double membrane
• Mitochondrial division=fission as bacteria
• Chloroplast
• Cyanobacteria=red algae chloroplasts
• Prochloron=plants and green algae
• Phaeophyta=brown algae and other photosynthetic protists
• Centrioles
• Spirochete bacteria
• Mitochondria
• Nonsulfur purple bacteria

Classification of protists

• Cell surface differences
• Locomotor organelles
• Cycst formation
• Nutrition
• Reproduction
• Binary fission
• Budding
• Schizogony
• Gamete formation
• Zygotic meiosis
• Intermiediary meiosis
• Five groups
• Heterotrophs w/no locomotion
• amoeba
• Photosynthetic
• Dinoflagellates, euglena, gold algae, red algae, kelp, green algae
• Heterotrophs with flagella
• Zoomastigina, ciliates(paramecium)
• Nonmotile spore formers
• plasmodium
• Heterotrophs with retricted mobility
• Water molds, rust
