Mitochondria divide by_____

Answer

**Step-by-Step Solution:**

1. **Identify the Organelle**: The question asks about the division process of mitochondria, which are organelles responsible for energy production in cells.

2. **Understand Mitochondrial Characteristics**: Mitochondria are unique because they contain their own DNA and have similarities to prokaryotic cells, which are simpler cells without a nucleus.

3. **Define Semi-Autonomous Organelle**: Due to their own DNA and ability to replicate independently, mitochondria are classified as semi-autonomous organelles.

4. **Determine the Division Process**: Mitochondria divide through a process similar to that of prokaryotic cells. This process is known as binary fission.

5. **Explain Binary Fission**: Binary fission is a type of asexual reproduction where an organism divides into two equal parts. In the case of mitochondria, they can undergo binary fission in two ways:
- **Midzone Fission**: The mitochondrion divides from the middle.
- **Peripheral Fission**: The mitochondrion divides from the outer edges.

6. **Conclude the Answer**: Therefore, the process by which mitochondria divide is called binary fission.

**Final Answer**: Mitochondria divide by **binary fission**.
