Mitochondria are the powerhouse of the cell because they supply power (energy) to all the cell of the body.
All living cells have mitochondria (cell organelle), are responsible for producing energy (called ATP) that the cell needs to function.
They are like power stations in our bodies, supplying energy to all cells for proper functioning.
If our cells do not have energy, then the tissues or body organs that are made up of cells do not work properly, in the same way that if power stations do not produce enough energy for the country there will be areas of blackout, where parts of the country cannot function.
