2024 Cell: The Unit of LifeMembrane Structure of Mitochondria and Chloroplast Medium Question 20 of 137 in Cell: The Unit of Life

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:

A Statement I is correct but statement II is incorrect.
B Statement I is incorrect but statement II is correct.
C Both statement I and Statement II are correct.
D Both statement I and Statement II are incorrect.

The answer is A.

Solution

Statement I is correct: both mitochondria and chloroplasts are double membrane bound organelles. Statement II is incorrect: the inner membranes of both mitochondria and chloroplasts are relatively impermeable, with specific transporters for selective transport. So Statement I is correct but Statement II is incorrect.

Concept Comparing permeability of mitochondrial vs chloroplast inner membranes
