Cell Membrane Cellular Transport

Our cell membrane only lets certain substance in and out of the cell.  This is called?

• Semi-Selectively Permeable

• Perforated

• Non-conductive

• Permeable

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
