How does surface area effect diffusion? - Answers

Surface area significantly affects diffusion by increasing the space available for molecules to pass through. A larger surface area allows more molecules to move across a boundary simultaneously, facilitating faster diffusion rates. This principle is evident in biological systems, where cells often have adaptations like microvilli to enhance their surface area for more efficient nutrient absorption. Conversely, a smaller surface area can limit the rate of diffusion, slowing down the movement of substances.
