Best Answer

The cell membrane and the cell wall is are composed of two different things. The cell membrane is made from phospholipid bilayers that becomes flexible by cholesterols. The cell wall is a rigid structure that surrounds the cell membrane that is either composed of cellulose, chitin, or peptidoglycan depending on the cell.

Why can molecules that are fat-soluble permeate across a cell membrane?

Cell membranes are composed of a lipid bilayer. Cellular fluid (cytosol) and the cell's organelles are contained by the cell's membrane, which is composed of a lipid bilayer. Lipids are a type of fat. Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol.


Does the cell wall surround the membrane?

What molecule makes up cell membranes?

Cell membranes are mainly composed of phospholipids. A phospholipid is a phosphate group with a fatty acid tail. Proteins are also present in cell membranes.
