Question

Select the wrong statement from the following:

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

Answer 1

The correct option is B

Both chloroplasts and mitochondria have an internal compartment, the thylakoid space bounded by the thylakoid membrane.

The correct option is B:

Explanation of the correct option:

1. Chloroplasts contain a sac-like structure called thylakoids.
2. Thylakoids are arranged in stacks and are called grana.
3. Thylakoids help in photosynthesis.
4. Since mitochondria are not the site for photosynthesis, hence it lacks thylakoids

Explanation of the incorrect option:

Option A:

Both chloroplasts and mitochondria are double membranous organelle having an outer and an inner membrane.

Option C:

Both chloroplasts and mitochondria contain DNA to synthesize the products by themselves, independent of the nucleus.

Option D:

The size of chloroplast is larger than mitochondria to absorb maximum sunlight for photosynthesis.

Final answer: Both chloroplasts and mitochondria have an internal compartment, the thylakoid space bounded by the thylakoid membrane is a wrong statement.
