Why does a cell of a growing multicellular organism need to divide with regards
to getting its necessary substances it
needs to survive?

A. If a cell gets too large, it will not get the
substances it needs due to diffusion
occurring a lot slower.
B. If a cell gets too large, it will get all the
substances it requires and thus large size is

C. If a cell gets too small, there is not enough

survive.
D. If a cell gets too small, it will not get enough
substances to support its life.
