Why Is a Large Surface Area: Volume Ratio Needed for Cells

question 47

Multiple Choice

Why is a large surface area: volume ratio needed for cells to function properly?

• A) Adequate surface area (plasma membrane) is needed to furnish nutrients to and expel wastes from the volume (cytoplasm).
• B) Smaller volumes reduce and larger surface areas reduce the cell's ability to bring nutrients in and get rid of waste.
• C) A smaller surface area allows the cell to increase its metabolic activity by bringing in even more nutrients than larger surface areas.
• D) The surface area and volume increase at the rate to ensure cell growth and reproduction.
