Question

What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?

Answer 1

A Small cell has a large surface area/volume ratio and therefore can exchange molecules with it's external environment rapidly.

So, Here cell with ratio 6:1 is smaller and have ability to better transportation across it's membrane as compared to other cell with ratio 3:1

Answer 2

A Small cell has a large surface area/volume ratio and therefore can exchange molecules with it's external environment rapidly.

So, Here cell with ratio 6:1 is smaller and have ability to better transportation across it's membrane as compared to other cell with ratio 3:1

Hope this helps!
