Which one is a self-replicating organelle?
Correct answer: D. Mitochondrion
- A. Ribosome
- B. Centriole
- C. Lysosome
- D. Mitochondrion
Explanation
Mitochondria are capable of self-replication through a process called mitochondrial fission. Mitochondria are double-membraned organelles found in eukaryotic cells, and they are often referred to as the "powerhouses of the cell" because they generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. Mitochondrialfission is the process by which a single mitochondrion divides into two daughter mitochondria. This division is essential for maintaining the population and distribution of mitochondria within the cell. It allows mitochondria to multiply in response to the cell's energy needs, adapt to changes in cellular conditions, and repair damaged mitochondria.
