Plasma membrane - phospholipids and protein and selective membrane
Explanation:
A cell wall of plant's cell is made up of cellulose that is embedded in a matrix of polymers such as pectin and lignin.However, cell wall of of an algae cell is made up of some other compounds such as calcium, polysaccharides like alginic acid etc. and glycoproteins. The major function of a cell wall is to provide shape and strength to the cell. It is semipermeable therefore it also allows passage of essential materials through it .
While a plasma memebrane is made up of phospholipid as it has a phospholipid bilayer that also has embedded proteins. It acts as a selectively permeable as it allows only some ions or organic molecules to pass through it and also regulate movement of substances in and out of cells.
Plasma membrane ; phospholipids and protein; selective membrane
Explanation:
The plasma membrane is the living boundary of a cell and is made of a phospholipid bilayer with embedded proteins. It is selectively permeable membrane and regulates the movement of substances across the membrane.
The cell wall is the outer boundary of the plant cells. It is rigid, permeable and made of cellulose, a polymer of carbohydrate. The cell wall gives strength to the cell.
