Answer
Mitochondria are known as the powerhouse of the cell because they carry out cellular respiration, in which glucose and other molecules are broken down to release energy that is stored as ATP. If all the mitochondria are removed from a eukaryotic cell, the cell would not be able to produce energy through cellular respiration. Without ATP, the cell could not carry out its energy-requiring activities such as the synthesis of materials, transport, and movement. As a result, the cellular activities would stop and the cell would eventually die.
