Cell Membrane

• The outer wall
• Thin layer of lipids
• Imbedded in this lipid layer are specialized
  protein doors
• Enter raw material
• Exit as finished or waste products

Cell Membrane

• Hydrophilic circles with hydrophobic tails.

• Tails always 'push' away from the water
• Causes the bi-layer.

Endoplasmic Reticulum

• The Transport and Communication organelle
• Network of membranes the connect the cell
  membrane to the nucleus

Golgi Bodies

• The packaging and delivery department
• Products (proteins) go through a final assembly
  and packaging

16
Mitochondria

• Powerhouse Organelle
• Manufacture ATP
• ATP is used as a source of energy for the cell.

Lysosomes

• Garbage Disposal
• Digestion of unwanted proteins

Vacuole

• Look like holes in Swiss cheese
• Empty spaces within the cell
• Often contain products to be removed from the
  cell.
