Strand 2: Structures & Processes

Movement Through Cell Membranes

Diffusion, osmosis and active transport across cell membranes.

Osmosis Simulator

Set the solute concentration on each side and predict water movement.

Left side

50%

solute concentration

Right side

20%

solute concentration

Net water movementleft

Water moves by osmosis from a region of low solute concentration (high water potential) to a region of high solute concentration (low water potential) through a partially permeable membrane.
