Given below are two statements:

Statement I: Mitochondria and chloroplasts both double membranes bound organelles.

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

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

Let us analyze each statement step-by-step to understand why the option "Statement I is correct but Statement II is incorrect" is the correct choice.

Analysis of Statement I:
Statement I says: "Mitochondria and chloroplasts both double membranes bound organelles."
According to cellular biology, both mitochondria and chloroplasts are semi-autonomous organelles that are indeed enveloped by a double membrane system consisting of an outer membrane and an inner membrane. This structural feature is a key piece of evidence supporting the endosymbiotic theory. Therefore, Statement I is correct.

Analysis of Statement II:
Statement II says: "Inner membrane of mitochondria is relatively less permeable, as compared chloroplast."
In biological membranes, the outer membranes of both mitochondria and chloroplasts contain porins (large channel proteins), making them highly permeable to small molecules and ions.
However, when comparing their inner membranes:
- The inner membrane of mitochondria is extremely selective and impermeable to most ions and polar molecules (requiring specific transporters), but the inner membrane of the chloroplast is similarly highly selective.
- Structurally and functionally, the inner membrane of the chloroplast is actually relatively more impermeable (less permeable) compared to that of the mitochondrion, or at least they are both highly impermeable, making the comparative claim in the statement incorrect or misleading. In standard textbook biology, the inner membrane of the chloroplast is considered the primary permeability barrier of the chloroplast, and the mitochondria's inner membrane is not "less permeable" relative to the chloroplast's inner membrane in a way that validates this statement. Thus, Statement II is incorrect.

Consequently, Statement I is correct but Statement II is incorrect.
