CELL MEMBRANE=1)Cell membrane is present in all types of cells. i.e human, animal, plant, bacterial etc.
2)
Cell membrane is an organelle of the cell. And is outermost cover in animals and humans. It provides shape to cell which is flexible.
3)
It is a lipid bilayer. And is made of lipo-proteins.
4)
This has the ability to contract. It is flexible to change the shape as needed.
5)
In Bacteria, cell membrane gives rise to flagella (movement) and pilli (reproduction) like structures.

**CELL WALL=1)
Cell wall is Present in only plant cells and bacterial cells.
2)
Cell wall is the outer non-living cover of the cell but not an organelle. It encloses cell membrane. It also provides a fixed shape.
3)
This is made of pectin, chitin, lignin etc. In bacteria it is made of glyco-proteins, glyco-lipds
4)
Cell wall is rigid with fixed shape. Any pressure application can break the wall
5)
While cell wall facilitates flagella and pilli through small apertures.
