Answer:

The greater the distance that a substance must travel, the slower the rate of diffusion.

Explanation:

Distance travelled: The greater the distance that a substance must travel, the slower the rate of diffusion. This places an upper limitation on cell size.
  • Let distance be d
  • Rate of diffusion be R

Here

[tex]\\ \rm\Rrightarrow R\propto \dfrac{1}{d}[/tex]

Rate of diffusion is inversely proportional to distance

  • Higher the distance lower the rate of diffusion
  • Lower the distance lower the rate of diffusion
