Solution
The correct option is D Glycocalyx
The cell envelope of a bacterial cell consists of three layers - the outermost glycocalyx, the cell wall and the innermost plasma membrane.
Glycocalyx is a sticky layer surrounding the bacterial cell. It could be in the form of a capsule or slime layer. The capsule is tightly bound to the cell wall. It is thick and tough whereas the slime layer is loosely bound to the cell wall.
The glycocalyx is followed by a cell wall that is made up of peptidoglycan. The cell wall determines the shape and provides structural support to the cell.
The cell wall is followed by a plasma membrane that is made up of phospholipids and proteins. The plasma membrane encloses cytoplasm which is the fluid matrix of the cell and has various components of the cell.
Nuclear membrane is absent in the bacterial cells.
