Answer:
It is important because if not then life would not exist at all except maybe in single cells forms
Step-by-step explanation:
The body is made of so many cells and without cell specialzation, the cells would not know what to do, they would all be the same. The liver is so different from the skin from the eyes, from the tongue, and so on. That is why we need it so our body can do what it is supposed to do.
Thatś only really one example but I hope it helps!
