    Data Sheet:

    Cell Size Lab

    Answer the following questions to help you understand the results of your cell size experiment.

    Pre-Lab Questions
    1. What is cell surface area-to-volume ratio, and why is it important in regards to cell size?

    2. In the lab, what do the potato pieces represent? What does the food coloring represent?

    Lab Questions
    Data
    3. Use the data table below to record your observations of how far the food coloring penetrated
    the potato pieces.

    Potato Piece Length Width Height Distance of Dye


    (cm) (cm) (cm) (cm)

    1 (small piece)

    2 (medium piece)

    3 (large piece)

    Results
    The following table provides the equations you need to determine the results of your
    experiment.

    Calculation for a Cube

    Volume V = length (L) width (W) height (H)

    Surface Area SA = 2(L)(W) + 2(L)(H) + 2(W)(H)

    Ratio ratio = SA V

    your calculations in the table below.

    Potato Piece Volume Surface Area Surface Area-to-Volume


    (cm) (cm)

    1 (small piece)

    2 (medium piece)

    3 (large piece)

    4. Which potato piece has the greatest surface area, and which has the greatest volume?

    5. Which potato piece has the smallest surface area, and which has the smallest volume?

    Analysis/Conclusion
    6. If each potato piece represents a living cell, and the food coloring is a substance needed within
    the cell, what problem might the largest cell have?

    7. According to your data, which cell was most successful at receiving the needed nutrient (food
    coloring) in the allowed time?

    8. Describe what type of surface area-to-volume ratio best meets the needs of living cells.
    Explain your answer.
