<h3>What is Cell membrane ?</h3>
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
- A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
- Biological membranes serve three main purposes. First, they prevent harmful substances from entering the cell. Second, they have receptors and channels that let certain molecules, like ions, nutrients, wastes, and metabolic products,
- Third, they divide metabolic processes that are necessary but incompatible that take place within organelles.
