The mitochondria

Options

A. divide by budding
B. divide by fission
C. divide by meiosis
D. do not divide

Answer

### Step-by-Step Solution:

1. **Understanding Mitochondria**: Mitochondria are known as the powerhouse of the cell, responsible for producing energy in the form of ATP through cellular respiration.

2. **Division Mechanism**: The question asks about how mitochondria divide. Mitochondria replicate independently of the cell cycle, similar to prokaryotic organisms.

3. **Binary Fission**: Mitochondria divide by a process called binary fission, which is a method of asexual reproduction commonly seen in prokaryotes. This means they split into two parts, each containing a copy of the mitochondrial DNA.

4. **Coordination with DNA Replication**: The division of mitochondria is coordinated with the replication of mitochondrial DNA. This ensures that each new mitochondrion has the necessary genetic material to function properly.

5. **Identification of Proteins**: Some proteins involved in the fission process have been identified, and abnormalities in these proteins can lead to mitochondrial diseases.

6. **Conclusion**: Based on this information, the correct answer to the question is that mitochondria divide by fission.

### Final Answer:
Mitochondria divide by fission.
