Xylem is not associated with translocation of

Options

A. Water
B. Minerals
C. Organic nitrogen
D. Photosynthates

Answer

**Step-by-Step Solution:**

1. **Understanding Xylem Function**: Xylem is a type of vascular tissue in plants primarily responsible for the transport of water and dissolved minerals from the roots to the rest of the plant. It plays a crucial role in maintaining plant hydration and nutrient supply.

2. **Identifying Translocation**: Translocation refers to the movement of substances within the plant. In the context of xylem, it specifically involves the upward movement of water and minerals.

3. **Analyzing the Options**:
- **Option 1: Water**: Xylem is responsible for the translocation of water. Therefore, this option is incorrect.
- **Option 2: Minerals**: Xylem also transports minerals dissolved in water. Hence, this option is also incorrect.
- **Option 3: Organic Nitrogen**: Xylem can transport certain organic compounds, but it is primarily associated with inorganic nutrients. However, it does play a role in transporting some nitrogenous compounds. This option is still incorrect.
- **Option 4: Photosynthates**: Photosynthates refer to the products of photosynthesis, primarily sugars like glucose. These are transported by phloem, not xylem. Thus, this option is correct as xylem does not translocate photosynthates.

4. **Conclusion**: The correct answer is that xylem is not associated with the translocation of photosynthates.

**Final Answer**: Xylem is not associated with translocation of **Photosynthates**.
