Select the wrong statement from the following

Options

A. both chloroplasts and mitochondria contain DNA.
B. the chloroplasts are generally much larger than mitochondria
C. both chloroplasts and mitochondria contain an inner and an outer membrane
D. both chloroplasts and mitochondria have an internal compartment, the thylakoid space bounded by the thylakoid membrane

Answer

To solve the question of selecting the wrong statement from the provided options, we can follow these steps:

### Step-by-Step Solution:

1. **Read the Statements Carefully**: Begin by examining each statement provided in the question. This will help in understanding what each statement claims about mitochondria and chloroplasts.

2. **Evaluate Statement 1**: The first statement claims that both mitochondria and chloroplasts contain DNA. This is true because both organelles have their own circular DNA, which makes them semi-autonomous.

3. **Evaluate Statement 2**: The second statement states that chloroplasts are generally larger in size than mitochondria. This is also true; chloroplasts are indeed the largest organelles in plant cells.

4. **Evaluate Statement 3**: The third statement mentions that both chloroplasts and mitochondria have an inner and outer membrane. This is correct as both organelles are double membrane-bound.

5. **Evaluate Statement 4**: The fourth statement claims that both chloroplasts and mitochondria have an internal compartment called the thylakoidal space bounded by the thylakoidal membrane. This is incorrect because the thylakoidal space is specific to chloroplasts. Mitochondria do not have this structure.

6. **Identify the Wrong Statement**: After evaluating all the statements, it is clear that the fourth statement is the wrong one, as it inaccurately describes the structure of mitochondria.

7. **Conclude the Answer**: Therefore, the answer to the question is that the wrong statement is statement number 4.

### Final Answer:
The wrong statement is: **"Both chloroplast and mitochondria have an internal compartment, the thylakoidal space that is bounded by the thylakoidal membrane."**
