Question

Select the wrong statement from the following :

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

Answer 1

Answer: (A)

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

Answer 2

Both chloroplasts and mitochondria contain DNA and are double membrane bound organelles having an inner membrane and outer membrane. Mitochondria occur in cytoplasm of both plants and animal cells. A mitochondria contains two chambers. The inner membrane forms mitochondrial cristae. Chloroplast is also a double membranous organelle but found only in plants. The membrane bound matrix of chloroplasts is stroma and inside the stroma thylakoids are present which form grana.
