Xylem is associated with translocation of

Options

A. Water and mineral salts
B. Organic nitrogen
C. Hormones
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Xylem Function**: Xylem is a type of vascular tissue in plants 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 the Translocation Process**: The primary function of xylem is to facilitate the translocation of water and nutrients. This process is vital for photosynthesis, growth, and overall plant health.

3. **Components of Xylem**: Xylem consists of various cell types, including tracheids and vessel elements, which are specialized for conducting water. The xylem also contains xylem parenchyma for storage and fibers for support.

4. **Mechanism of Water Movement**: Water moves through xylem via a combination of root pressure, capillary action, and transpiration pull. Transpiration, the loss of water vapor from plant surfaces, creates a negative pressure that helps draw water upward.

5. **Conclusion**: Therefore, the xylem is primarily associated with the translocation of water and dissolved minerals in plants.
