Osmosis in Potatoes Quiz

What is the first step in preparing potato cylinders for an osmosis experiment?

• Weighing the potato

• Using a cork borer to take cores

• Boiling the potato

• Cutting the potato into slices

Why is it important to trim the potato cylinders to the same length?

• To ensure they fit in the test tubes

• To ensure consistent surface area for osmosis

• To make them easier to weigh

• To make them look uniform

How do you calculate the percentage change in mass of the potato cylinders?

• Divide the final mass by the initial mass and multiply by 100

• Subtract the initial mass from the final mass and multiply by 100

• Divide the change in mass by the original mass and multiply by 100

• Add the initial and final mass and divide by 2

What does a percentage change in mass closest to zero indicate about the sucrose solution?

• It is hypertonic with the potato cells

• It is isotonic with the potato cells

• It has a higher concentration than the potato cells

• It has a lower concentration than the potato cells

What can be determined by plotting the results on a graph and finding where it crosses the x-axis?

• The time taken for osmosis to occur

• The exact sucrose concentration with no mass change

• The final mass of the potato cylinders

• The initial mass of the potato cylinders
