4. Osmosis The diffusion of water through semi-permeable membranes from
phenomenon
high water potential. low water potential.
or ( salt conc.) ( salt conc.)
Osmatic pressure:
The pressure causes the diffusion of water through the semi-permeable and this is due
to the difference in conc. of the (solutes) in water on the 2 sides of the membrane.
The relation between the conc. of solutes in the solution and osmotic pressure of the
solution is directly proportional relation.
