State the difference between:Cell wall and cell membrane.

1.	State the difference between:Cell wall and cell membrane.
Answer» Cell wall 1. It is made up of cellulose. 2. It gives shape and rigidity to the plant cell. 3. It is a non-living structure. 4. It protects the cell from the entry of disease-causing agents, as well the underlying protoplasm against mechanical injuries. Cell Membrane 1. It is very thin, delicate and flexible. 2. This allows the entry of certain molecules only, while holding back the others. 3. It is living structure. 4. It has fine pores in it, through which only certain substances carfpass in and out, while others cannot.
