However; the plasma membrane is made of phospholipids and is flexible and selectively permeable, while the cell wall is stiff cellulose, giving the cell a rigid ship, and it is not permeable. Cell walls are found in plant and bacteria cells, but in animal cells whereas the plasma membrane is found in all cell types.
