Water Potential

Key Questions

  • Answer:

    The water potential gradient determines the direction of osmosis. It goes from high to low water potential.


    This is because n a high water potential area there is a bigger number of free water molecules. Free here means they are not attached to other solute molecules forming a hydration shell.

    This video discusses the changes which occur in plant cells when they are placed into hypertonic and hypotonic solutions.

    Hope this helps!

  • If there is a higher concentration of solute,more water will be likely to travel in through a partially permeable membrane (Osmosis).
