Select the wrong statement from the following

1. Both chloroplasts and mitochondria have an internal compartment, the thylakoid space bounded by the thylakoid membrane
2. Both chloroplasts and mitochondria contain DNA
3. The chloroplasts are generally much large than mitochondria
4. Both chloroplasts and mitochondria contain an inner and an outer membrane

Correct answer: Both chloroplasts and mitochondria have an internal compartment, the thylakoid space bounded by the thylakoid membrane

Solution

The thylakoid space is a feature of chloroplasts, not mitochondria. Mitochondria have an inner membrane folded into cristae, so the statement claiming both share a thylakoid space is wrong.
