Osmosis And Diffusion

1. Osmosis is

The diffusion of sucrose

The diffusion of IKI

The diffusion of glucose

The diffusion of water

2. In this lab the dialysis tubing represents

Mitochondria

Plasma Membrane

Chloroplast

Nucleus

3. How does water move?

Always from higher potential to lower potential

Always from lower potential to higher potential

Movement varies depending on mass

Cannot tell until you do the lab

4. Which molecule is larger, glucose or IKI?

IKI

Glucose

Can't tell

5. Which solution list below is most hypertonic relative to distilled water?

0.0 M sucrose

0.2 M sucrose

0.4 M sucrose

0.6 M sucrose

6. What is the purpose of IKI in the lab?

To indicate the presence of glucose

To react with the dialysis tubing

To indicate the presence of starch

To color the solution red

7. In the lab how can you tell whether the dialysis bags gained or lost water?

By the change in color

By the change in volume

By the change in mass

You cannot tell

8. How is the presence of glucose detected?

Glucose test strip

IKI

Change in mass

All of the above

9. Which of the following is true of sucrose?

It is non-polar

It is table sugar

It is the same as starch

It will not dissolve in water

10. A 0.2 M solution of sucrose will have

.2 molecules of sucrose per milliliter of water

.2 moles of sucrose per milliliter of water

.2 moles of sucrose per L of water

.2 moles of sucrose per L of solution
