OSMOSIS WITH LIVING PLANT CELLSC.a. ProcedureThis experiment is designed to demonstrate the principles of osmosis with livingplant tissues. Using a corkborer, bore two equal-sized cylinders of freshly cut rawpotato. Feel them and note the degree of firmness. Place one potato piece in a culturedish containing enough five percent salt solution to cover the potato completely.Place the second potato piece in a culture dish containing the same amount ofdistilled water. After about 20 minutes, examine both pieces of potato and note anychanges in their degree of firmness.b.
