Which of the following is called the powerhouse' of the cell? (1) Nucleus (2) Lysosome (3) Chromosome (4) Mitochondrion
by

1 Answer

Answer :

(4) Mitochondrion Explanation: Mitochondria are sometimes described as "cellular power plants" because they generate most of the cell's supply of adenosine tri-phosphate (ATP), used as a source of chemical energy. In addition to supplying cellular energy, mitochondria are involved in other tasks such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth.
