उत्तर
Mitochondria and plastids are two different structures, and they have specific functions. Mitochondria are found in both plants and animals, whereas plastids are found only in plants. The main role of mitochondria is to provide energy to the cells for carrying out their various functions. If there had been no difference between mitochondria and plastids, there would have been no structure that would provide energy, and thus all the processes that take place in the cell would cease.
