Given below are two statements :

Statement I : Mitochondria and chloroplasts are both double membrane bound organelles.

Statement II : Inner membrane of mitochondria is relatively less permeable, as compared to chloroplast.

In the light of the above statements, choose the most appropriate answer from the options given below :

1. Statement I is incorrect but Statement II is correct.

2. Both Statement I and Statement II are correct.

3. Both Statement I and Statement II are incorrect.

4. Statement I is correct but Statement II is incorrect.

Best answer

Answer: 4. Statement I is correct but Statement II is incorrect.

Key idea: both organelles are bounded by two membranes, and in both the inner membrane is the selective barrier.

  • Statement I is correct. Mitochondria and chloroplasts are both double-membrane bound organelles.
  • Statement II is incorrect. The outer membrane of each organelle is freely permeable, and the inner membrane of each is selectively permeable. NCERT gives no basis for saying the mitochondrial inner membrane is less permeable than that of the chloroplast.

Statement I correct, Statement II incorrect: option 4.
