How does the surface area of a cell impact the rate of diffusion?
A larger surface area speeds up diffusion.
A smaller surface area speeds up diffusion.
Surface area does not affect diffusion.
Surface area affects diffusion differently depending on the type of molecule.
Explanation
A larger surface area allows for more molecules to diffuse across the membrane simultaneously.
