Eukarya (eukaryotic); archaea and eukarya are more closely related: within the domain eukarya, there are 4 different groups of organisms: Animalia (animals), plantae (plants), fungi (fungi), protists (eukaryotic organisms that are not animals, plants, or fungi) 19-1: spherical (coccus, cocci, rod-shape, corkscrew-shape, diversity of bacteria and archaea, structure. Cheese and yogurt: bacteria in our intestine produce vitamin (ex. Infectious protein particles devoid of any genetic material: misfolded proteins, prion-caused diseases may be heritable, how can a protein be infectious, proposed model for prion replication, misfolded versions of the normal protein are the infectious particles. Kingdom protista: what is a protist, eukaryotic, unicellular or colonial (grey area in between colonial and multicellular, highly diverse, protist phylogeny, polyphyletic- multiple origins, diversity in protista, diversity in terms of impact to humans, many environmentally beneficial, photosynthesis.
