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.

determine if osmosis or simple diffusion A crystal of blue copper sulfate is placed in a test tube of water. The next day, the solid is gone, but the water is evenly colored. A fresh potato is peeled, weighed, and soaked in a strong salt solution. The next day, it is discovered that the potato has lost a significant amount of mass. A perfume bottle is opened, and soon the odor can be sensed in all parts of the room. Garden grass wilts after being exposed to dry chemical fertilizer. Plant seeds soaked in water swell and become several times as large as before soaking. A sugar cube is dropped into a cup of hot water, and without being stirred, all of the liquid becomes sweet tasting.
