Explanation

**Step-by-Step Solution:**

1. **Understanding Water Transport in Plants:**
- In plants, water is primarily transported through the xylem, which consists of specialized tissues that facilitate the movement of water and dissolved minerals from the roots to the leaves.

2. **Role of Water Potential:**
- Water potential is a measure of the potential energy in water, and it determines the direction of water movement. Water moves from areas of higher water potential to areas of lower water potential.
