Xylem help in the transport of

Options

A. Water
B. Minerals
C. Hormones
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Xylem**: Xylem is a type of vascular tissue in plants responsible for the transport of water and dissolved minerals. It is essential for the plant's hydration and nutrient supply.

2. **Function of Xylem**: The primary function of xylem is to conduct water from the roots to the aerial parts of the plant, such as stems and leaves. This process is crucial for photosynthesis and overall plant health.

3. **Components Transported by Xylem**: Xylem not only transports water but also carries water-soluble minerals and hormones that are essential for plant growth and development.

4. **Mechanism of Transport**: The movement of water and minerals through xylem occurs primarily due to root pressure, which is generated when water is absorbed by the roots from the soil. This pressure helps push the water upward through the xylem vessels.

5. **Direction of Transport**: The transport of water and minerals via xylem is typically upward, from the roots to the shoots (aerial parts of the plant).

6. **Conclusion**: Therefore, xylem helps in the transport of water, minerals, and hormones, making the correct answer "all of the above."
