1. The Plasma Membrane • the skin of the cell

2. Function • Gives support to cell • Transports substances into/out of the cell to maintain gradient • Proteins in membrane communicate outside the cell

4. Function of Parts • Lipid Bilayer – keeps foreign objects out of the cell • Membrane Channel – lets particular substances in and out of the cell • Glycoproteins – interacts with other cells

5. TEM of Membrane

6. Analogy The plasma membrane is to the cell as skin is to a human
