Document Summary

Chapter 5 - algae & evolution of land plants: what are the different types of algae? (part of the protista kingdom, simple photosynthetic aquatic organisms (some unicellular, others multicellular), plankton = microorganisms suspended in h2o. A. 1. phytoplankton (photosynthetic plankton) = diatoms + dinoflagellates. A. 1. a) important b/c bottom of food chain in ocean + prov. A. 1. b) if population of them isn"t controlled > red tide (neurotoxins, can be poisonous to us + fish) [mainly dinoflagellates that cause this] A. 1. c) dinoflagellates also live with coral that"re responsible for productivity & abundance of life in coral reefs. A. 1. d) oil + natural gas comes from remains of plankton: red + brown algae = (brown is) only in ocean, both are multicellular. B. 3. red is commonly used for nori (seaweed in sushi) ex. seaweed, kelp harvested for cell wall material (industrial use) B. 4. not plants, protista: green algae = fresh/salt water, plants, some unicellular, some colonial.
