Two spherical animal cells differ only in radius. Cell A has a radius of \(5\ \mu\text{m}\) and Cell B has a radius of \(10\ \mu\text{m}\). The time required for a small solute to diffuse across a cell is proportional to the square of the cell's radius. Which cell will reach diffusion equilibrium faster, and by what factor does its diffusion time compare to the other cell?

Answer Options

Correct Answer A. Cell A diffuses faster; its diffusion time is one‑fourth that of Cell B.
B. Cell A diffuses faster; its diffusion time is one‑half that of Cell B.
C. Cell B diffuses faster; its diffusion time is one‑fourth that of Cell A.
D. Cell B diffuses faster; its diffusion time is one‑half that of Cell A.
Correct Answer
A
Correct Option:
Cell A diffuses faster; its diffusion time is one‑fourth that of Cell B.
