Consider two imaginary cells. Both are cube shaped (the same dimension in all directions) The first cell has a side length of 10 micrometers. The second has a side length of 100 micrometers. Calculate the surface areas and volumes of both of these cells then calculate the sa/v for each of them. The SA, V and Sa/V dived out of each of theses cells. which one of these would be most efficeint at feeding itself? Why? If we added a third cell with a side length of 50 micrometers how would its feeding efficiency compare to our first two cells ( no calculations needed) Why ?

Finally if our least efficient cell needed to increase its feeding effiency to match the most efficient cell what is one way it might do it? Oh – that’s without actually changing its volume. Be specific about how the cell must change.
