A difference can be seen in the average rate of conductivity depending on surface area because the Agar cubes with a larger total surface area are able to diffuse the ions faster. When the Agar cube has larger surface area, more area is exposed to the water in order to evenly spread faster from a high concentration of ions (Agar cubes) to a low concentration of ions (water), therefore increasing the conductivity rate and diffusion.
According to the error bars in the graph, there is a greater error in trials with a bigger surface area. This happened because it becomes more difficult to cut the Agar cubes when the dimensions become smaller. There is no overlap of the error bars, although they are very close to overlapping. This shows that the data is not very reliable, yet even with errors it is …show more content…
When comparing the Agar cubes to cells, the surface area: volume ratio is essential to living organisms. It is important for the cells to be able to diffuse nutrients and release waste through the cell membrane and into/out the cell. The larger the ratio, the more cell membrane will be able to cover this job. It is also important for cells to have a larger surface area than volume, like shown in this Agar cube experiment. In real life, most cells are not larger than 1mm because smaller cells allow nutrients to diffuse more efficiently and diffuse waste efficiently, too. When the cell volume is too big, the diffusion rate becomes too slow that the cell will eventually die or
