The light reactions occur in the ____ and the dark reactions take place in the ____
|
|
Chloroplast / thylakoid membrane
|
|
|
stroma / thylakoid
|
|
|
mesophyl / stomata
|
|
|
thylakoid membrane / stroma
|
Explanation:
Detailed explanation-1: -(i) Light reactions occur in grana thylakoids whereas dark reactions occur in stroma of chloroplasts.
Detailed explanation-2: -The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.
Detailed explanation-3: -The dark reactions of photosynthesis occur in the stroma of the chloroplast where they utilize the products of the light reaction. In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.
