Name different theories to explain water translocation.

Explanation

**Step-by-Step Text Solution:**

1. **Root Pressure Theory**:
- This theory explains that water translocation begins with the absorption of ions from the soil by the roots.
- As ions accumulate in the root cells, they create a higher concentration of solutes inside the roots compared to the surrounding soil.
- Water moves into the roots from the soil to balance the concentration of solutes, leading to an increase in pressure within the root cells.
- This pressure, known as root pressure, pushes water upward through the xylem, but it is limited to small heights in the stem.
