Question: 174. 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 statement, choose the most appropriate answer from the options given below :
(1) Both Statement I and Statement II are correct
(2) Both Statement I and Statement II are incorrect.
(3) Statement I is correct but Statement II is incorrect.
(4) Statement I is incorrect but Statement II is correct
Answer: Option (3)
Explanation:
Statement I is correct because both mitochondria and chloroplasts are double membrane bound organelles. Each has an outer membrane and an inner membrane enclosing their internal structures.
Statement II is incorrect because the inner membrane of mitochondria is highly selective and less permeable to ions and molecules,
whereas in chloroplasts, the inner membrane is relatively more permeable compared to the mitochondrial inner membrane.
Therefore, Statement I is correct but Statement II is incorrect,
making Option (3) the correct answer.
