Cell Transport Review

When does diffusion occur across a membrane?

• when the concentration of particles is different on each side of the membrane

• when the concentration of particles is equal on both sides of the membrane

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

• when water moves across the membrane

Why will an animal cell burst if it is surrounded by fresh water?

• because solutes will move out of the cell
