Why are all different parts of the cell necessary

So the organism can function properly. The nucleus is the main control center. It tells certain things what to do. Like it sends DNA strands out to copy itself. Tell me if you need more examples or if this helps tell me and thank me.

Different parts of the cell do different things but they all contribute to the same body (the cell itself). What I am saying is that different parts of the cell, organelles, have different jobs but the all have their part in helping the cell live. Like if a cell did not have a Mitochondria, the cell would die off because the job of this part and it is as important as the nucleus and the mitochondria digests the food and spreads energy for the cell. If that stops, the nucleus and the rest of the organelles would not function. so if one organelle does not function, the whole cell is effected. Therefore, all parts of a cell is necessary.
