AIR TEST QUESTION: The diagram shows a time-lapse movement of particles across the membrane of a cell. The particles have characteristics that allow them to pass freely. Select ALL the statements that would describe the moving particles.

• The particles do not have a charge.

• The movement across the membrane requires energy from ATP.

• The particles could be small like water or oxygen.

• The movement across the membrane does not require energy.

• The particles could be large like proteins or carbohydrates.

Why has water moved into the cell in the hypotonic solution?
