[Discworld] Are The Great A'tuin's cells supersized proportionately to his own giant sized form, or does he just have more of them?

Great A'tuin just has more cells, he/she's just a very large creature. 

A tiger doesn't have bigger cells than a mouse, despite being much bigger, they just have many more of them. The same applies to Great A'tuin, who is a space turtle and started off as a small hatchling before growing to his/her current size.
