Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In chloroplasts, the inner membrane is relatively less permeable than the outer membrane. Reason (R): The inner membrane of the chloroplast infolds to form organized flattened membranous sacs called thylakoids. In the light of the above statements, choose the correct answer from the options given b

Step-by-step solution

Assertion (A) is true: As per NCERT, chloroplasts are double membrane-bound organelles, and of the two, the inner chloroplast membrane is relatively less permeable. Reason (R) is false: Unlike the inner mitochondrial membrane which forms infoldings called cristae, the inner membrane of the chloroplast does not form thylakoids through infolding. Thylakoids are separate, organized flattened membranous sacs present within the stroma. Thus, Assertion (A) is true but Reason (R) is false. Answer: Assertion (A) is true bu
