Question

Which of the following is common in chloroplast and mitochondria?

• A. Both are involved in respiration
• B. Both are found in animal cells
• C. Both contain small amount of DNA
• D. Both are not a component of endomembrane system

Answer 1

The correct option is C

Both contain small amount of DNA

Both chloroplast and mitochondria are membrane-bound cell organelles forming a part of the endomembrane system. Mitochondria are found in both plant and animal cells but chloroplast is absent in animal cells. Both chloroplast and mitochondria contain a small amount of DNA, RNA and ribosomes (70 S type), thus involved in protein synthesis. Mitochondria are site or respiration, while chloroplasts are the site of photosynthesis.
