Bacteria shapes - Cocci, bacilli, vibrios (comma shaped), spirilla (spiral), pleiomorphic (various shapes) adherence molecules to stick to surfaces - - mediated by pili, fibers of pilin proteins possess other proteins on their tips for sticking - a sex pilus is used for conjugation - some microbes use an extension of the cell envelope tipped by a "holdfast" of paysaccharides 3 parts of flagella - - filament - hook protein - basal body active transport - - all microorganisms active tr...
