Question

Which cell would be able to supply itself most efficiently with nutrients diffusing in from the outside—a large cell or a small cell? Why?

Answer 1

A small cell because it has a higher surface area to volume ratio

Answer 2

So if you imagine a bacteria, it can survive using diffusion, but mammals need systems, like the respiratory system and circulatory system to supply oxygen and nurtrients to cells, because bacteria is so much smaller, it doesn't have a long diffusion pathway and needs less stuff
