The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Respiration**: Respiration can occur in two forms: aerobic (with oxygen) and anaerobic (without oxygen). We need to identify which of the given options can respire anaerobically. 2. **Analyzing the Options**: - **Seeds**: Germinating seeds can respire anaerobically. When seeds germinate, they often do not have access to oxygen due to the tough seed coat, which limits gas exchange. They utilize stored nutrients for energy through anaerobic respiration. - **Leaves**: Leaves primarily carry out aerobic respiration, as they have access to oxygen through stomata. - **Stems**: Stems also require oxygen for respiration and do not typically undergo anaerobic respiration. - **Roots**: While roots can sometimes respire anaerobically in waterlogged conditions, they generally require oxygen for efficient respiration. 3. **Conclusion**: Among the options provided, only **seeds** are capable of respiring in the absence of oxygen, particularly during the initial stages of germination. 4. **Final Answer**: The correct answer is **seeds**. ---
