The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Question**: The question asks where minerals are absorbed in plants. 2. **Understand the Options**: Typically, the options provided may include various parts of the plant such as leaves, stems, roots, and flowers. 3. **Focus on Root Functionality**: The primary function of roots is to anchor the plant and absorb water and nutrients from the soil. 4. **Identify the Specific Area**: Within the root system, the root hair zone is crucial for absorption. This area contains root hairs, which are specialized structures. 5. **Role of Root Hairs**: Root hairs significantly increase the surface area of the roots. This adaptation allows for more efficient absorption of water and mineral ions, such as nitrates, from the soil. 6. **Conclusion**: Therefore, the correct answer is that minerals are absorbed in the root hair zone of the roots. **Final Answer**: Minerals are absorbed in the root hair zone. ---
