Exotoxins and endotoxins (1 um = 1/1,000,000 m) Modifications for survival: prokaryotic flagellum, pili, endospores, actinomycetes (fungus like) Functions: protect from phagocytosis, adherence, prevent desiccation, feeding, flagella. The prokaryotic cell: axial filaments, fimbriae and pili. Two different types based on structure: gram , gram . Structures internal to cell wall: the plasma membrane.
