What is diffusion?

• When molecules move from a low concentration to a high concentration

• When molecules move from a high concentration to a low concentration.

• When there is no movement of molecules

• When molecules move everywhere regardless of concentration

Equilibrium is when....

• there is a large amount of substance on the inside of the cell and a small amount in the outside solution

• there is a small amount of substance on the inside of the cell and a large amount in the outside solution

• there is an equal amount of substance on either side of the cell membrane

• there are no particles on either side of the the cell membrane

Diffusion moves along the __________

• concentration gradient

• Avogadro's constant

• conservation of energy

When does diffusion stop?

• After a day and a night

• When the particles are evenly spread out

• When there are no particles left

• When all the particles leave the system

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
