What is the relationship between rate of ion exchange and surface-to-volume ratio?

2. What is the advantage of a cell that has a large surface-to-volume ratio?

3. Which is more efficient at exchanging materials, a small or a large cell? Explain.

4. Some cells in the body have adapted to the task of absorption and excretion of large amounts

of materials. In what ways have these cells adapted to this task?

5. How does cell growth affect the cell’s surface-to-volume ratio?

6. In order for a cell to continue being efficient at exchanging materials, what must it do to

maintain its surface-to-volume ratio as it grows larger?
