WebThe experiment showed that if the surface area volume ratio gets bigger the diffusion rate increases. It means that when the surface area volume ratio increased the amount of Sulphuric acid that entered the agar block decreased hence supported the hypothesis. So the bigger surface area volume ratio causes increasing diffusion rate. Web(larger cells need more energy to sustain essential functions) The rate of material exchange is a function of its surface area (large membrane surface equates to more material movement) As a cell grows, volume (units 3) increases faster than surface area (units 2), leading to a decreased SA:Vol ratio If metabolic rate exceeds the rate of ... fix duplicate ip addressWebThe volume is 1^3 = 1 cubic centimetre.

WebMar 17, 2024 · Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but ... WebSep 15, 2024 · September 15, 2024 by Alexander Johnson. Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
