Fun Facts about Cell Membrane
- The cell membrane is composed of the double layer of phospholipids with embedded proteins.
- The protein in the lipid bilayer plays a crucial role in the movement of substances across the cells membrane.
- The cell membrane is selectively permeable, such that it only allows certain molecules to pass through them.
- The cell membrane also consists of carbohydrates, which helps in cell adhesion and communication.
- The cell membrane is also known as the plasma membrane and is found in every living organism.
Thus, the cell membrane is a protective layer that is permeable to certain molecules and plays a vital role in cell metabolism.
