Which of the following pair of organelles does not contain DNA?

Options

A. Mitochondria and Lysosomes
B. Chloroplast and Vacuoles
C. Lysosomes and Vacuoles
D. Nuclear envelope and Mitochondria

Answer

To determine which pair of organelles does not contain DNA, we can analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Organelles in Each Pair**:
- Pair 1: Mitochondria and Lysosomes
- Pair 2: Chloroplast and Vacuole
- Pair 3: Lysosomes and Vacuole
- Pair 4: Nuclear Membrane and Mitochondria

2. **Check for DNA Presence in Each Organelle**:
- **Mitochondria**: Known as the powerhouse of the cell, mitochondria contain their own DNA (mtDNA).
- **Lysosomes**: These organelles are involved in digestion and waste removal but do not contain DNA.
- **Chloroplasts**: These organelles are responsible for photosynthesis and also contain their own DNA.
- **Vacuoles**: Generally involved in storage and do not contain DNA.
- **Nuclear Membrane**: This surrounds the nucleus, which contains the cell's DNA.

3. **Analyze Each Pair**:
- **Pair 1 (Mitochondria and Lysosomes)**: Mitochondria have DNA, but lysosomes do not. So, this pair contains one organelle with DNA.
- **Pair 2 (Chloroplast and Vacuole)**: Chloroplasts have DNA, but vacuoles do not. This pair also contains one organelle with DNA.
- **Pair 3 (Lysosomes and Vacuole)**: Both lysosomes and vacuoles do not have DNA. This pair contains no organelles with DNA.
- **Pair 4 (Nuclear Membrane and Mitochondria)**: Both have DNA (nuclear membrane surrounds the nucleus which contains DNA, and mitochondria have their own DNA).

4. **Conclusion**: The only pair that does not contain any organelles with DNA is **Pair 3: Lysosomes and Vacuole**.

### Final Answer:
The correct answer is **C: Lysosomes and Vacuole**.
