what happen's if one cell organelle quits working how does it affect the cell?
Well that'd depend entirely on which organelle, how damaged it was, etc.
I'd say the result would normally be either of two scenarios:
A) The cell manages to keep on working, perhaps repairing/replacing the damaged organelle.
B) Apoptosis. The 'self destruct button' gets triggered.
One can "cure" yeast of their mitochondria. They grow more slowly and require fatty acid supplementation.
