An analysis of the xylem exudates shows that much of the nitrogen travels as

Options

A. Inorganic ions
B. Nitrate and nitrites
C. Organic form i.e., amino acids and amides
D. Molecular nitrogen

Answer

To solve the question regarding the form in which nitrogen travels in xylem exudates, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Xylem Exudates**:
- Xylem exudates are the fluid that is released from the xylem tissue of plants. This fluid contains various nutrients and compounds that are transported from the roots to other parts of the plant.

2. **Identifying Nitrogen Forms**:
- Nitrogen can be present in various forms in plants, including inorganic forms (like nitrate and nitrite) and organic forms (like amino acids and amides).

3. **Analyzing the Options**:
- The question mentions different forms of nitrogen: inorganic ions (like nitrate and nitrite), organic forms (like amino acids and amides), and molecular nitrogen.

4. **Focusing on Organic Nitrogen**:
- Among the organic forms, amino acids (e.g., glutamine and asparagine) are significant as they are commonly involved in nitrogen transport and storage in plants.

5. **Conclusion**:
- Based on the analysis, it is concluded that much of the nitrogen in xylem exudates travels in the form of organic compounds, specifically as amino acids and amides.

### Final Answer:
Much of the nitrogen in xylem exudates travels as organic forms, specifically amino acids and amides.
