BIO153H5 Lecture Notes - Lecture 9: Thiomargarita, Phototroph, Photoheterotroph
Document Summary
No one looking for cure - no researchers. Just had no clue of such small particle/bacteria: yersinia pestis - still out there today, eukarya. First forms of life - oldest life forms on earth. Created by biofilms - layers of bacteria or archaea. Example: pre-cambrian stromatolites (glacier national park, usa)s, extant stromatolites (shark bay australia - still living) Genetic recombination - al 3 below increase genetic diversity. Not random - have in membranes that are able to specifically target genetically material. Sex pilus - pipe that goes from one to another bacteria. Generally asexually, but have other tricks up sleeves. Light as an energy source and co2 as a carbon source. Except for thiomargarita namibiensis - which is 0. 2mm. Save energy by reducing volume on a physiological level. Exactly it: the area in which you produce, use, and get energy, the volume of the organism and the size of the surface. Volume grows way quicker - the bigger you get.
