D. OSMOSIS WITH LIVING PLANT CELLS C. a. Procedure This experiment is designed to demonstrate the principles of osmosis with living plant tissues. Using a corkborer, bore two equal-sized cylinders of freshly cut raw potato. Feel them and note the degree of firmness. Place one potato piece in a culture dish containing enough five percent salt solution to cover the potato completely. Place the second potato piece in a culture dish containing the same amount of distilled water. After about 20 minutes, examine both pieces of potato and note any changes in their degree of firmness. b.

Sterile normal saline is used in most surgical procedures as an irrigation solution. During certain surgical procedures, such as those for malignancy, the surgeon may request that sterile water be used for irrigation instead of saline following excision of the cancerous mass. Why is normal saline usually used in healthy tissues?

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.

ACTIVITY: DIFFUSION Procedures: 1. Fill one glass cup with hot water. Fill the second glass with cold water. 2. Put 1-2 drops of red food coloring in the hot cup, and 1-2 drops of blue food coloring in the cold one. 3. Watch and wait for color to disperse entirely. Observe. 4. What would you observe? Which one dispersed quickly? What would be the reason? 5. Get two containers. One is wide and the other one is narrow. 6. Fill both container with the same temperature of water. 7. Put one drop of food coloring in each container and compare their rate of diffusion. 8. Observe. Which container demonstrated slower rate of diffusion? Explain.
