Rate of osmosis

[jsmith613]

is the rate of osmosis dependant on the length of the diffusion pathway?

[JackBean]

depends, whether the difference of concentrations will be the same per length unit or per whole length

[jsmith613]

lets say osmosis occurs between plant and solution
solution has lower water potential

will a thicker cell wall (increased diffusion pathway) reduce rate at which water is lost by plant?

[JackBean]

mainly, thicker cell wall will function as barrier, so the rate of diffusion will be for sure affected.
