g or smaller cell? Explain why.
g g g g




Answer I believe it is the smaller cell that will breathe at a more active rate because in or

der for respiration to occur efficiently and more actively the surface area to volume rati

o is very critical; also, if the larger surface area is present then the diffusion of gases occu

r at a higher rate; so, larger cells will have a smaller surface to volume ratio and diffusio

n that will occur at a slower rate creating a less active respiration; and, on the other han

The smaller cell. Cells need to remain relatively small because as a cell expands the amo

tive because relative to its volume, its surface area is larger than a bigger cell.With a larg
