The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Rod Cells**: Rod cells, also known as macrosclerates, are a type of sclerenchyma cell. They are characterized by their elongated, rod-like shape. 2. **Identifying the Function**: Rod cells provide structural support to the plant. They are a reduced form of sclerenchyma and are important for the mechanical strength of various plant parts. 3. **Location of Rod Cells**: These cells are typically found in the outer layer of the seed coat of legumes. Their presence helps protect the seed and contributes to its overall strength. 4. **Distinguishing from Other Cell Types**: It is important to differentiate rod cells from other types of sclerenchyma cells, such as brachysclerids (stone cells) which are more rounded and provide different types of support. 5. **Conclusion**: Therefore, rod cells are elongated sclerenchyma cells found in the outer layer of legume seed coats, providing mechanical support. ---
