Cell membrane also known as…
Plasma membrane and cell surface membrane
What is the cell surface membrane made of? Simple
Phospholipid bilayer
Where is cell surface membrane found?
Found on surface of animal cell
Found under cell wall in a plant
What does the cell surface membrane do? Simple
Regulates the movement of substances in and out of the cell due to its semi permeable membrane
What is the structure of the cell wall?
Rigid and made up of microfibrils of cellulose
What is the function of a cell wall?
Protects and supports a cell so it doesn’t change shape
