Which one is most efficient converter of sunlight ?

Options

A. Sugarcane
B. Rice
C. Wheat
D. Papaya.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which plant is the most efficient converter of sunlight. This relates to how effectively different plants can perform photosynthesis, particularly in terms of carbon dioxide fixation.

2. **Identifying Plant Types**: The options provided are sugarcane, rice, wheat, and papaya. These plants belong to different photosynthetic pathways: C3 and C4.

3. **C3 vs. C4 Plants**:
- C3 plants (like rice, wheat, and papaya) use the Calvin cycle for carbon fixation. This process is less efficient in hot and dry conditions because the stomata can close to conserve water, limiting CO2 intake.
- C4 plants (like sugarcane) have a different mechanism that allows them to fix CO2 more efficiently, even when stomata are partially closed. They initially fix CO2 into a 4-carbon compound (oxaloacetic acid), which is then converted to sugars.

4. **Efficiency of Sugarcane**: Sugarcane, being a C4 plant, is more efficient in utilizing atmospheric CO2 for photosynthesis. This efficiency allows it to convert sunlight into chemical energy more effectively than C3 plants.

5. **Conclusion**: Based on the above reasoning, the most efficient converter of sunlight among the options given is **sugarcane**.

**Final Answer**: Sugarcane is the most efficient converter of sunlight.
