Surface Area To Volume Ratio Essay

How does surface area to volume ratio affect the rate of diffusion?

As the gelatin cube sizes were cut into smaller pieces, the surface area to volume ratio increases. Surface area to volume ration is very important in living organisms, since all the nutrients and oxygen need to diffuse through the cell membrane into the cells. The surface area to volume ratio affects the rate in which the salt diffused through the solution by how the salt diffused out of the gelatin and into the water this relates to small cells that have a faster rate of diffusion for the nutrients and oxygen to diffuse into the cell and out of the cell quicker. Whereas if the cells were bigger, the rate of diffusion for the nutrients and oxygen to diffuse into the cell would take too long and the cell would probably not survive. So the surface area to volume ratio in cells is vital since the smaller they are the faster the rate of diffusion of the nutrients and oxygen can go in and out for the cell to be able to grow and survive.

Unicellular organisms who have a larger surface area compared to its volume can rely on diffusion to move substances into and out of the cells. By having a larger surface area nutrients and other substances can pass

These error bars are there to show how a general idea of how precise the data or measurement is or in opposite how far the data or measurement is from the real data might be. These error bars can often represent standard deviation or uncertainties. In this graph, the error bars are extremely low on the first two. However, on the last bar in where it is recorded the smallest cube sized gelatin, the error bar is quite high. This issue might be because of how small the size of the gelatin cube is, in where it can affect the way you measure it since it might be due to inaccurate measurements of how the cube was cut into or the salt concentration in that cube due to human
