Solution
Assertion – Cyclic photophosphorylation occurs in stroma Reason – Stroma membrane lacks PS II and NADP reductase.
To determine the correct answer, we need to evaluate the assertion and reason given.
Assertion: Cyclic photophosphorylation occurs in stroma. Reason: Stroma membrane lacks PS II and NADP reductase.
Based on the information provided, we can conclude that both the assertion and reason are correct. The reason provided explains why cyclic photophosphorylation occurs in the stroma. Therefore, the correct answer is option A) Both Assertion & Reason are correct and Reason is a correct explanation for the Assertion.
