The cell as an entity doesn't reproduce, but that's not bigger a problem than the fact that an animal as an entity doesn't reproduce either. The ideas of the extended phenotype work inward also: the genes that do reproduce are the genes that codify reproduction. All other genes and structures of the cell are merely helping that happen. They vary because that increased the long-term chances of reproduction happening. From that point of view, there's no need to invoke processes, nor entities like organisms or cells: what's being reproduced are the genes to reproduce, and the laws governing it are just mathematics, like with a prion or a virus.
