Front

What is osmosis?

Back

The movement of water molecules across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher solute concentration than the cell, while hypotonic solutions have a lower solute concentration.
