Gram Stain A staining method that distinguishes between two different kinds of  bacterial cell walls. Gram-positive Describing the group of bacteria with a cell wall that is structurally  less complex and contains more peptidoglycan than that of gram- negative bacteria.  Gram-positive bacteria are usually less toxic than  gram-negative bacteria. Gram-negative Describing the group of bacteria with a cell wall that is structurally  more complex and contains less peptidoglycan than that of gram- positive bacteria.  Gram-negative bacteria are often more toxic than  gram-positive bacteria. Capsule (1) A sticky layer that surrounds the cell walls of some  prokaryotes, protecting the cell surface and sometimes  helping to glue the cell to surfaces. (2) The sporangium of a  bryophyte (moss, liverwort, or hornwort).
