How root pressure develops in roots?

Explanation

### Step-by-Step Solution:

1. **Mineral Ion Uptake**: The process begins with the absorption of mineral ions from the soil by the root cells. Roots have specialized structures that facilitate this uptake.

2. **Deposition in Xylem**: Once absorbed, these mineral ions are transported into the xylem vessels, which are part of the plant's vascular tissue responsible for water and nutrient transport.

3. **Osmotic Potential Changes**: The accumulation of these mineral ions in the xylem leads to a decrease in osmotic potential. Osmotic potential is a measure of the tendency of water to move into a solution, and a lower osmotic potential means that the solution is more concentrated.
