D: Osmosis

Here's a step-by-step explanation:

1. Osmosis is the process by which water moves from an area of high concentration (such as the soil) to an area of low concentration (such as the root cells).

2. The root hair cells, which are in direct contact with the soil, have a higher concentration of solutes (like minerals and nutrients) than the surrounding soil. This makes the soil water potential higher than the root hair cell.

3. Due to this difference in water potential, water moves into the root hair cell by osmosis.

4. The water then continues to move from cell to cell within the root and up into the rest of the plant through a combination of osmosis and capillary action.

5. This process continues as long as there is a higher concentration of water in the soil than in the plant. If the plant loses too much water (for example, through transpiration), it may wilt as the cells lose turgor pressure.
