Give reason why the phenomenon of osmosis cannot be demonstrated by using a boiled potato.

Osmosis is the phenomenon when the two solutions having different osmotic concentration are separated by a semi- permeble membrane and the movement of solvent takes place from a region of low concentration of the solute to a region where there is high concentration of the solute or from a region where there is high concentration of solvent to a region where there is low concentration of solvent.

Another condition required for osmosis to occur is the presence of intact semi permeable membrane i.e cell membrane. But on boiling potatoes, cell membrane do not remain intact or become dead, so the process of osmosis can not be demonstrated by boiled potatoes.
