Question:
Two different bacteria have radii of 1 micrometer and 5 micrometers. What is the surface area of each cell?
How does the surface area compare with the volume for each cell—that is, what is the surface-area-to-volume ratio? Why is the larger cell able to obtain more molecules through diffusion? Why is it nonetheless more challenging for the larger cell to meet its needs through diffusion?
Recall that the surface area of a sphere is 4pr 2 and the volume of a sphere is 43 pr 3.
