Document Summary
Structural and functional diversity in protista: protista exhibit more structural and functional diversity than any other group of eukaryotes, they are most nutritionally diverse of all eukaryotes, some protists reproduce asexually while others reproduce sexually. The 4 supergroups of eukaryotes: look at figure 28. 2, excavates, sar, achaeplastids, unkionts endosymbiosis. Have two equal sized nuclei and multiple flagella. Have reduced mitochondria called hydrogenosomes that generate energy anerobically and release hydrogen gas. Include trichomonas vaginalis, the pathogen that causes yeast infections in human females. Kinetoplastids: have single mitochondrion with an organized mass of dna called a kinetoplast. Include free-living consumers of prokaryotes in freshwater, marine, and moist terrestrial ecosystems: this group includes genus trypanosome, members use sleeping sickness in humans. Transmitted by african tsetse fly: another pathogenic trypanosome in latin america causes chagas" disease transmitted by bloodsuckers (kissing bugs) can lead to chf.
