Solution

The correct option is C Assertion is correct but Reason is incorrect
Chloroplasts are large organelles bounded by a double membrane i.e., the inner membrane and the outer membrane. These membranes constitute the chloroplast envelope. The outer membrane of the envelope contains porins because of which it is freely permeable to small molecules. In contrast, the inner membrane is impermeable to ions and metabolites, which can only enter chloroplasts via specific membrane transporters.
So, the correct option is 'Assertion is correct but Reason is incorrect'.
