The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Assimilatory Power**: - Assimilatory power refers to the energy and reducing power generated during the light-dependent reactions of photosynthesis. 2. **Light Reactions**: - In the light reactions, sunlight is captured by chlorophyll, leading to the production of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules are crucial for the next stage of photosynthesis. 3. **Role of ATP and NADPH**: - ATP serves as an energy source, while NADPH provides the reducing power necessary for the conversion of carbon dioxide (CO2) into carbohydrates during the dark reactions (Calvin cycle). 4. **Dark Reactions**: - The dark reactions utilize the ATP and NADPH produced in the light reactions to synthesize glucose from CO2. This process is also known as carbon fixation. 5. **Conclusion**: - Therefore, the term "assimilatory power" specifically refers to the combination of ATP and NADPH produced during the light reactions, which are then utilized in the dark reactions for the synthesis of carbohydrates. 6. **Final Answer**: - The correct answer to the question "Assimilatory power is" is ATP and NADPH2 (option 3). ---
