The root hair cells has a special structure to help it absorb water from the soil efficiently.
1. Elongated structure that protrudes out to the soil
- This is to increase the surface area to volume ratio; thereby increasing the rate of uptake of water from the soil to the cell.
2. Large vacuole
- The root hair cell has a large vacuole to maximize the amount of water capacity of the cell; thus, the cell is able to absorb and store more water.
3. Cell sap
- The cell sap of the root hair cell has a lower water potential than the water in the soil. Thus, the water from the soil moves into the cell via osmosis.
