Question 9 • AP Biology - SC5182 A
A cell’s surface-to-volume ratio improves when it has more surface area relative to its volume. Increasing surface area while keeping volume about the same improves the ratio, and dividing a cell into many smaller cells increases their combined surface area relative to their total volume. Changing to a shape with a better surface-to-volume ratio can also help. Simply increasing the cell’s volume, or increasing its length along with both surface area and volume, does not necessarily improve the ratio.
