Why mitochondria called power house of cell?

Mitochondria are sometimes described as "cellular power plants," because they generate most of the cell's supply of ATP, used as a source of chemical energy. The number of mitochondria in a cell varies widely by organism and tissue type. Many cells possess only a single mitochondrion, while others can contain several million mitochondria. Although most of a cell's DNA is contained in the cell nucleus, mitochondria have their own independent genomes. According to the endosymbiotic theory, mitochondria are descended from free-living prokaryotes.
