I am so lost and I'm hoping for a bit of help....

How does volume/surface area affect the rate of diffusion?

Has anyone done that lab with the agar cubes where you put them in NaOH and calculate the rate of diffusion? What type of graphs should I make? What should I be comparing?

Any helpful tip/hints that would help me?

Thanks!!!

we have. although i cant give you a direct answer. think about the nutrients that the cell needs to absorb. what if the cell got too big. what happens to the distance from the nucleus. keep in mind that nutrients must go from the plasma membrane to the nucleus.

hope i helped.

Don't forget that surface area would also mean more...well, surface, for stuff to go in/out of whatever it might be :D
