Diffusion Osmosis Lab

Diffusion Osmosis Lab. Osmosis. Osmosis = the movement of water molecules from a region of higher water potential to a region of lower water potential through a partially permeable membrane. Osmosis is considered in terms of water potential and solute potential. Water Potential.

What is Water Potential?

What is Water Potential?. Water potential. the force responsible for movement of water in a system Has the symbol psi Is measured in bars or megapascals. It is a measure of the free energy of water which is less when it is has to surround solutes. We are really stuck here, YUK!.
