The higher the ratio, the faster the rate of diffusion
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
For example, the amount of nutrients a cell can absorb are proportional to its surface area.
All chemical reactions take place on surfaces = so very important
so it can get more sun
Surface area directly affects the rate of diffusion by providing more area for molecules to interact; a larger surface area leads to faster diffusion rates because there are more opportunities for molecules to move across the membrane. With a greater surface area, more molecules can pass through the cell membrane at the same time, increasing the overall rate of diffusion.
According to fick's law rate of diffusion =(proportional to)= Surface area x Diffusion gradient Diffusion Pathway thickness So for a sufficient rate of diffusion, Surface area must be large The diffusion pathway is already at it's minimun of 1 cell thick and the gradient is harder to adjust. There are around 600 million alveoli in the lungs that have a cummulitive surface area of around 70m2.
The surface area to volume ratio of a cell affects the rate of diffusion in that the higher the ratio, the faster the rate of diffusion. This is a directly proportional relationship.
Three main factors that affect diffusion are temperature (higher temperature increases rate of diffusion), concentration gradient (greater difference in concentration leads to faster diffusion), and surface area (larger surface area allows for more diffusion to occur).
Factors that affect simple diffusion include concentration gradient (higher concentration difference leads to faster diffusion), temperature (higher temperatures increase diffusion rate), surface area available for diffusion (larger surface area allows for faster diffusion), and characteristics of the molecules themselves (size and solubility).
That depends upon the shape of the particles. * If they are spherical, the surface area is 4*pi*r^2, where r is the radius of the particle. * If they are cuboidal, the surface area is b*w*h, where b, w, h are the lengths of the sides
The diffusion rate is directly proportional to the concentration gradient, the surface area available for diffusion, and the permeability of the membrane through which diffusion occurs.
The higher the ratio, the faster the rate of diffusion
Diffusion is a type of passive transport. The factors that influence diffusion include: concentration gradient, size of molecule involved, distance the molecule has to travel, temperature, solubility of the molecule and surface area.
Large surface area: A greater surface area allows for more molecules to come into contact with the surface, increasing the rate of diffusion. Thin membrane: A thin exchange surface reduces the distance that molecules have to travel to diffuse across the surface, speeding up the diffusion process.

Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
