Explanation:
Mitochondria are known as the powerhouse of a cell. It is the site where cellular respiration takes place. As a result of cellular respiration, ATP is produced which is the main energy source for cells to carry out their normal processes. Mitochondria is present both in the plant as well as the animal cells.
