Solution
The correct option is C Assertion is correct but Reason is incorrect
- Photosynthesis is the process by which green plants use the energy of light to convert carbon dioxide and water into the simple sugar glucose.
- Dark reactions are called dark reactions because they are not directly depended on light but they are dependent on products of light reaction i.e ATP and NADPH2. Hence Dark reaction can take place in the absence of light. Hence reason is incorrect.
- The dark reaction of photosynthesis uses products of light reaction i.e ATP and NADPH2.Hence Assertion is correct.
- So, the correct answer is 'Assertion is correct but Reason is incorrect'.
