Diagram imaging the present knowledge of the cell envelope structure of Synechococcus. Present observations taken together suggest that the spicules (SP) extend through the surface layer (S) and outer membrane (OM) to contact the cell membrane (CM) (as shown in the cutaway of the peptidoglycan layer (P)).
