Practice questions testing deep understanding of light and dark reactions, chloroplast structure, and limiting factors.
Q1. In a laboratory experiment, a plant is provided with water that contains a radioactive isotope of oxygen (O18), but the carbon dioxide provided contains normal oxygen (O16). After photosynthesis, where will the radioactive oxygen (O18) be found: in the glucose produced, or in the oxygen gas released into the air? Justify your answer.
Q2. Assertion (A): The 'Dark Reaction' of photosynthesis only occurs at night in complete darkness. Reason (R): The Dark Reaction (Calvin Cycle) does not directly require light; it uses the ATP and NADPH produced during the light reaction to convert CO2 into glucose.
