Cell wall is an additional covering over the cell membrane in plant cells. It gives shape and rigidity to these cells.
The cell membrane is flexible and semi-permeable and hence cannot fight the adverse variations on its own. Therefore a stiff outer covering is present in plant cells which protects and gives shape and rigidity to the cell. This additional layer is called the cell wall. It is made of cellulose.
