For this activity, we had to make cube shaped models to represent cells. Then we had to compare surface area, volume, and surface area to volume ratio (SA:V) between the cells.
Cell A:
length of one side=1cm
Surface area= 6cm^2
Volume= 1cm^3
SA:V= 6
Cell B:
Length of one side= 2cm
Surface area= 24cm
Volume=8cm
SA:V=3
cell C:
length of one side= 3cm
Surface area=54cm
Volume=27cm
SA:V=2
Cell D:
Length of one side=4
Surface area=96cm
Volume=6cm
SA:V=1.5
1) What does it mean if the surface area to volume ratio is less than one?
It means that the cell is larger enough to t nutrients get into it. It also means that it has a larger surface area and volume.
2) What does it mean if the surface area to volume ratio is greater than one?
It means that the cell is small so less nutrients can get into it. It also means that it has a smaller surface area and volume.
3) What does it mean if the surface area to volume ratio is equal to one?
It means that the cell is perfectly fine as it is balanced.
Am I correct, I'm not too sure
