A) cell membrane \[\to \] glycocalyx\[\to \] cell wall
B) glycocalyx \[\to \] cell wall \[\to \] cell membrane
C) cell wall \[\to \] glycocalyx \[\to \] cell membrane
D) glycocalyx \[\to \] cell membrane \[\to \] cell wall
Correct Answer: B
Solution :
[b] Bacterial cell envelope consists of three components glycocalyx, cell wall and cell membrane. Glycocalyx - It is the outermost 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 component of cell envelope.
