Assertion: In light reaction of photosynthesis, light is required for the functioning of PS I and PS II, and production of NADPH and ATP.
Reason: Dark reaction does not occur in light.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
C.
If assertion is true but reason is false.
Light reactions of photosynthesis take place in the presence of light. These involve photolysis of water and production of assimilatory power (NADPH + ATP) through PS I and PS II.
Dark reactions of photosynthesis catalyse assimilation of CO2 to carbohydrates. Dark reactions are light independent reactions, hence can take place both in the light as well as in the dark
