LIFESCI 1 Lecture Notes - Lecture 13: Ciliate, Calcium Carbonate, Plasmodium
Document Summary
Eukaryote organism that is not an animal, plant, or fungi. Protist that is most closely related to animals. Entamoeba histolytica: the infectious agent in amoebic dysentery. Cellular slime molds unicellular, feed on soil bacteria. Photosynthetic eukaryotes: chloroplasts evolved from cyanobacteria living as endosymbionts with eukaryotic cells. Red algae chloroplasts & cyanobacteria have similar structure. Symbiosis: chloroplasts evolved from cyanobacteria living as endosymbionts with eukaryotic cells. Primary endosymbiosis eukaryote engulfs cyanobacterium and become green alga. Chloroplasts still contains some genetic material and can replicate by itself. Eukaryotes acquired photosynthesis multiple times by repeated episodes of endosymbiosis. Bacteria protect host cell from low oxygen & high h2s conditions. Includes green algae, red, algae, and land plants. Diversity of green algae closest relatives of land plants. Coralline red algae have calcium carbonate in cell walls. Allows for use of different niches -> red algae can grow in deep water. Stramenopiles have hairy flagellum and smooth flagellum at some point.
