Three gel cubes similar to those from the previous screens have been placed in a colored solution that seeps into the gel much like nutrients enter a cell. Use the slider to see how the solution affected the gel cubes after some period of time. 2. How does this model support the conclusion that cells need to have a high amount of surface area relative to their total volume?

These gel cubes can be thought of as representing individual cells. As the cubes interact with their surroundings based on the amount of surface area and volume they have, the efficiency movement of substances in and out of cells depends on the two attributes as well. Greater surface area will mean more efficient rates of diffusion, which implies a smaller surface area to volume ratio is ideal for a biological cell.

Hope that answers the question, have a great day!
