Answer 2

Cell wall is the outermost covering of the cell . It is only present in plant cell. It is non living. It supports and protect the cell. Cell membrane is present both in plant and animal cell it is the outermost covering of the cell but is only covered by cell wall in plant cell. It is a living structure made of cellulose. It allow only some selective particles to move around it and thus called semi permeable membrane also. It protects and give the cell a shape.
