Answer Key / Explanation : (b) -

(b)

Bacterial cell envelope consists of three components glycocalyx, cell wall and cell membrane

Glycocalyx It is the outermert mucilage layer of the cell envelope

Cell Wall It is rigid solid covering, which provides shape and structural support to the cell. Cell wall lies between plasma membrane and glycocalyx

Plasma/Cell Membrane It is selectively permeable covering of the cytoplasm that forms the innermost components of cell envelope
