D. Has nodes and internodes

Answer

To solve the question "Ginger is a stem which can be differentiated from root because it", let's analyze the options provided and understand the characteristics of ginger.

### Step-by-Step Solution:

1. **Identify the Structure of Ginger**:
- Ginger is classified as a rhizome, which is a type of modified stem. It grows horizontally underground.

2. **Examine the Options**:
- **Option A: Grows parallel to the ground**: While ginger does grow horizontally, this characteristic is not exclusive to stems; some roots can also grow parallel to the ground.
- **Option B: Stores food**: Both stems and roots can store food, so this does not differentiate ginger from roots.
- **Option C: Contains chlorophyll**: Generally, stems may contain chlorophyll, but roots do not. However, this is not the primary characteristic that distinguishes ginger as a stem.
- **Option D: Has nodes and internodes**: This is a key feature of stems. Stems have nodes (where leaves and buds arise) and internodes (the segments between nodes), while roots do not have these structures.

3. **Conclusion**:
- The most distinguishing feature of ginger, which allows it to be differentiated from roots, is that it has nodes and internodes. Therefore, the correct answer is **Option D: has nodes and internodes**.

### Final Answer:
**D. has nodes and internodes.**
