Plastid differs from mitochondria on the basis of one of the following features. Mark the right answer

Options

A. Presence of two layers of membrane
B. Presence of ribosome
C. Presence of chlorophyll
D. Presence of DNA

Answer

To determine how plastids differ from mitochondria, we need to analyze the features of both organelles.

### Step-by-Step Solution:

1. **Identify the Organelles**:
- Plastids (including chloroplasts) are organelles found in plant cells.
- Mitochondria are organelles found in both plant and animal cells.

2. **Examine Membrane Structure**:
- Both plastids and mitochondria have a double membrane structure. This means that the presence of two layers of membrane is not a distinguishing feature.

3. **Check for Ribosomes**:
- Both plastids and mitochondria contain ribosomes. Therefore, the presence of ribosomes is also not a distinguishing feature.

4. **Look for DNA**:
- Both plastids and mitochondria have their own DNA, which is circular and similar to bacterial DNA. This feature does not differentiate them either.

5. **Evaluate the Presence of Chlorophyll**:
- Chloroplasts, a type of plastid, contain chlorophyll, the green pigment essential for photosynthesis. Mitochondria do not contain chlorophyll and are not involved in photosynthesis.

6. **Conclusion**:
- The key distinguishing feature between plastids and mitochondria is the presence of chlorophyll in plastids, specifically in chloroplasts, which is absent in mitochondria.

### Final Answer:
The correct answer is **the presence of chlorophyll**.
