Water Potential |
A measure of the concentration of water molecules that are 'free' to diffuse. Adding solutes to water, lowers the concentration of 'free' water and hence lowers water potential. |
|
|
Osmosis |
Osmosis is diffusion of water from regions of high water potential to a region of low water potential down the water potential gradient through a partially permeable membrane |
|
|
Water Potential |
Highest Water Potential - Pure Water - No Solute dissolved |
|
|
Water Potential |
Lower Water Potential (-10kPa) - Dilute Solution - Small amount of solute dissolved |
|
|
Water Potential |
Very low water potential (-500kPa) - Concentrated Solution - Large amount of solute dissolved. |
