Paul [167]

Answer:

Size of particle.

Explanation:

Size of the particles that are diffusing is the factors that greatly affect the rate of diffusion. The rate of diffusion decreases if the thickness of the membrane becomes doubled while on the other hand, if the surface area of the membrane increases it doubled the rate of diffusion of the cell.
