Cell Membrane and Transport Short

Which statement best describes the cell membrane?

• The protective outer layer that controls what enters and leaves the cell.
  
• Stores information on DNA molecules / Directs and controls the activities of the cell.
  
• A folded membrane that moves materials around inside cells / Also acts as the site of manufacturing materials needed by the cell.
  
• The smallest organelle with a huge job / Makes proteins, which are the building blocks of the body.
