• energy
• oxygen
• water

During osmosis

• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration to a area of low concentration
