Use the models that you created in Lesson 2, Lab 1 to help you answer the following question.
Compare the surface area to volume ratio of a large cell to that of a small cell.

Why does the ratio of surface area to volume increase with the decrease in cell size?


A. A larger cell has more surface area than volume.
B. A smaller cell has more surface area than volume.
C. A smaller cell has more volume than surface area.
D. A smaller cell has an equal ratio of surface area to volume

B. A smaller cell has more surface area than volume. This allows for more reactions to occur across the various membranes of the cell.

Answer:

B

Explanation:

This is a question more about understanding ratios than understanding cells.

A surface area to volume ratio (S/V) in a size-decreasing cell would increase due to a more significant loss in volume that in surface area. In reality, both decrease (surface area AND volume), but as we are talking about a ratio, this one would go up due to a more dramatic decrease in volume.
