Question

Why are most cells so small?

A- Large cells cannot reproduce

B-Trillions must be able to fit inside a human body

C-Only small cells are able to use ATP

D-They need to have a large ratio of surface volume

Answer 1

cells must be small to have a large surface to volume ratio. The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

Answer 2

So it's D?
