BIOL 123 Lecture Notes - Lecture 16: Symbiogenesis, Green Algae, Red Algae
Document Summary
Land plants and related algae share similar genetic features. Green algae (chlorophytes) in land plants for aquatic animals, model organism, and sources of reneweable oil supplies. Occur in fresh waterm ocean, and on land. Cells contain some kind of plastids and photosynthetic pgiments that are present. Some are responsible for harmfuk aquatic growths but others are as useful as food. Red appearance of these algage are caused by photosynthetic pigments that are. Plastids of red algae resemble those of green algae and land plants (and differ for. Called primary plastids thoughtto have originated via primary endosymbiosis. Primary endosymbiosis- hetertrophic host cells captured cyanobacterial. Primary plastids and primary endosymbiosis absent from green algae and land plants most other algae) cells via phagocytosis but did not digest them. These endosymbiotic cyanobacteria evolved into primary plastids. All cells of plants green algae and red alge have one or more plastids and most of these organisms are photsynthetic.
