Which of the following cell organelles is lack of DNA ?

Options

A. Mitochondria
B. Chloroplast
C. Mitoplast
D. Lysosome

Answer

To determine which cell organelle lacks DNA, we can analyze the options provided: mitochondria, chloroplast, mitoplast, and lysosome.

### Step-by-Step Solution:

1. **Understanding Cell Organelles**:
- First, we need to know what each of the listed organelles is and their functions.
- Mitochondria are known as the powerhouse of the cell and are involved in energy production.
- Chloroplasts are involved in photosynthesis in plant cells.
- Mitoplasts are a type of mitochondria that lack some components but still retain DNA.
- Lysosomes are involved in breaking down waste materials and cellular debris.

2. **Analyzing DNA Presence**:
- **Mitochondria**: These organelles contain their own DNA, which is usually circular and is involved in encoding proteins necessary for their function.
- **Chloroplasts**: Similar to mitochondria, chloroplasts also have their own DNA, which is essential for their role in photosynthesis.
- **Mitoplasts**: These are modified mitochondria and still contain DNA.
- **Lysosomes**: These organelles do not contain DNA. They are membrane-bound vesicles filled with enzymes that digest cellular waste and are often referred to as the "suicide bags" of the cell.

3. **Conclusion**:
- After analyzing all the options, it is clear that lysosomes are the only organelles listed that do not contain DNA. Therefore, the correct answer is **lysosome**.

### Final Answer:
The cell organelle that lacks DNA is **lysosome**.
