Diffusion

If the solute cannot permeate the membrane, what will happen here when diffusion occurs?

• The water will move the left side to the right side.

• The water will move from the right side to the left side.

• The red particles will move from the left side to the right side.

• The red particles will move from the right side to the left side.
