The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks which plant has petioles that expand and become green to synthesize food. 2. **Identifying the Plants**: The options provided are Solanum, Pisum sativum, Venus flytrap, and Australian acacia. 3. **Analyzing the Australian Acacia**: The Australian acacia is known to be a xerophytic plant, which means it has adaptations to survive in conditions with limited water availability. 4. **Role of Petioles in Australian Acacia**: In the case of the Australian acacia, the petioles can expand and become flattened and green. This structure is referred to as a "phyllode." 5. **Function of Phyllodes**: Phyllodes are capable of photosynthesis, allowing the plant to synthesize food even in conditions where leaves may be scarce or adapted for water conservation. 6. **Conclusion**: Based on the characteristics of the Australian acacia, it is concluded that this plant is the one where the petioles expand and become green to synthesize food. 7. **Final Answer**: The correct option is **Australian acacia**. ---
