What are the differences between cell membrane and cell wall ?

Dear Student,

Here is the answer to your question,

Cell wall
Cell membrane
The cell wall is an additional protective, rigid structure present outside the cell membrane.
The cell membrane is porous in nature and helps in the inward and outward movement of substances.
It is present only in plant cells
Present in both animal and plant cells
Plant cell wall is composed of cellulose.
Cell membrane is composed of a lipid bilayer, with a polar head towards the outer side, and hydrophobic tails towards the inner side.
Plants cells do not move from one place to another and hence they require rigidity which is provided by the cell wall.
The cell membrane is the outer boundary of the cell, which separates one cell from the other. It also separates the contents of the cell from its surrounding medium.

Hope this answer helps,

Cheers!!
