Cell walls are only found in plant cells and are used primarily to create structure, but cell membranes are found in all cells. The bulk of the membrane is composed of a double layer of lipids called the lipid bilayer. Inside the bilayer there is a layer of cholesterol to keep the membrane fluid.

Yogita Ingle 7 years, 1 month ago

The cell membrane is made up of lipids like cholesterol and proteins. 50% of all types of protein found in a cell are in the cell membrane. Cell membrane is also called plasma membrane. It makes the boundary of a cell. It is composed of protein and lipid. It is porous and allows various materials to pass through it. Cell membrane is semi-permeable in nature which means it allows selected materials to pass through it.
