Out of peroxisomes, lysosomes and mitochondria, single membrane covering occurs in

Options

A. Both peroxisomes and lysosomes
B. Only peroxisomes
C. All the above
D. None of the above

Answer

To determine which of the organelles—peroxisomes, lysosomes, or mitochondria—has a single membrane covering, we can analyze each organelle based on their structural characteristics.

### Step-by-Step Solution:

1. **Identify the Organelles**: We have three organelles to consider: peroxisomes, lysosomes, and mitochondria.

2. **Analyze Lysosomes**:
- Lysosomes are membrane-bound organelles that contain digestive enzymes.
- They are responsible for breaking down waste materials and cellular debris.
- **Conclusion**: Lysosomes have a single membrane covering.

3. **Analyze Peroxisomes**:
- Peroxisomes are also membrane-bound organelles.
- They contain oxidative enzymes that are involved in various metabolic processes, including the breakdown of fatty acids and detoxification of hydrogen peroxide.
- **Conclusion**: Peroxisomes also have a single membrane covering.

4. **Analyze Mitochondria**:
- Mitochondria are known as the powerhouse of the cell and are involved in energy production through cellular respiration.
- They are characterized by having a double membrane structure, with an outer membrane and a highly folded inner membrane.
- **Conclusion**: Mitochondria do not have a single membrane covering.

5. **Final Comparison**:
- From the analysis, both lysosomes and peroxisomes have a single membrane covering, while mitochondria have a double membrane.
- Therefore, the correct answer is that both peroxisomes and lysosomes have a single membrane covering.

### Final Answer:
The correct option is **both peroxisomes and lysosomes**.
