Document Summary
*parts of the chapter he doesn"t mention in the lecture don"t worry about* Ernest haeckel: introduced term protists and phylogeny. Protists: represent a separate kingdom kingdom of primitive forms . Used knowledge of the tree of life to classify organisms based on their morphology. Darwin = actual origin of the tree of life . A eukaryote that is neither a fungus, plant, nor an animal (very diverse) Aquatic - able to find in freshwater, marine water or bloodstream (parasites) Nutritionally diverse - able to be photo-, chemo-or mixotrophs (both photo and chemo) Stentor (ciliate) - unicellular, microscopic, lives in freshwater and is chemoheterotroph (eats bacteria) Delesseria sanguinea (red alga) - multicellular, macroscopic marine, photoautoroph. *protists are no longer viewed as a kingdomy. *four supergroups of eukaryotes - protists can be found in each of the four. Mitochondria and plastids were formerly small prokaryotes living within larger host cells. Endosymbiont = a cell that lives w/in a host cell.
