2.  Root  Delicious  Irish

3. Diffusion of water through a cell membrane Hypertonic Lower concentration of water than in the cells Delicious Irish Root

4. Step 1: Cut up 3 identical pieces of potato. Step 2: Prepare a 3% salt hot, cold, and room temperature water bath. Step 3: Let potato pieces soak for 30 minutes. Step 4: Lightly dry and record the new mass. Initial mass of potato pieces: 2.7 grams

5.  Starting Mass: 2.7 grams  Ending Mass: 2.7 grams  Solution of 3% salt water  Boiled for 30 minutes NO MASS CHANGE

6.  Starting Mass: 2.7 grams  Ending Mass: 2.7 grams  Solution of 3% salt water  In freezer for 30 minutes NO MASS CHANGE

7.  Starting Mass: 2.7 grams  Ending Mass: 2.6 grams  Solution of 3% salt water  Soaked for 30 minutes 3.7% MASS LOST

8. VELOCITY: The speed of a molecule must be large enough to pass through the cell membrane. The cold water is a prime example of this. The molecules were not moving fast enough, and there for could not pass through Denaturation: When proteins lose their tertiary and secondary structures due to trauma or heat. The hot water was too hot and caused to proteins to destabalive. Molecules could not pass through the damaged proteins

9.  Although we got different data than expected, the reasons for those fluctuations is known. In the future, cooler hot water and warmer will be used so that a change in mass will be present.  COLD : 3.7 g  HOT : 3.7 g  ROOM: 3.6 g
