Which cellular organelle/part is present in all cells and to maintain homeostasis?

One important organelle that helps maintain homeostasis by moving supplies from one part of the cell to the other is the endoplasmic reticulum.

But,it may also be called Organelle

because an Organelle that helps maintain homeostasis by moving supplies from one part of the cell to the other is the Endoplasmic reticulum.

Hope this helps :)

It might. it might because if you think about if they discovered if we came from (lets say something funny like aliens) and thy found cells that matched and they would have t do more research about it but would most probably change their theory.
