For the first part, we put "cells" of different sizes into colored solution and then take them out after a certain amount of time. We measured the volume of which the solution diffused into, and found out that the bigger and thicker the cell is, the slower the solution diffuses.
For the second part of the lab, we put a "cell" that contains glucose and starch solution into water. After a while, we took it out, and tested if there was starch or glucose in the "water." The result is that there was glucose in it, but there wasn't any starch in it. It is because starch is too big to get through the cell membrane.
