The Cell Nucleus

The structure and internal functioning of every one of your cells is largely the same. The cell nucleus as the boss, the mitochondria as power plants, the ATP as energy storage, the endoplasmic reticulum as the intestine, the Golgi apparatus as an enzyme producer and the cell membrane as the outer shell that holds everything together.

Each of your cells has its own metabolism: water, nutrients and oxygen have to enter, metabolic products need to be taken out for health and medical purposes.
