Answer:
No I do not think that all of the cells in an animal are the same. All of the cells complete different things. For example, Mitochondria cells break down sugars and other compounds into celluar energy, while the skin cells are busy producing Keratin. This shows that no two cells are exactly the same.
Hope this helps!
