what will happen if cell sap of root hair cells contain

If the cell sap of root hair cells contains a high concentration of ions, then more water will enter the root cells by osmosis. This is because the greater amount of ions in the cell sap creates an osmotic gradient between the soil and the root hair cells, causing water to move from an area of high concentration (soil) to an area of low concentration (root hair cells) . The high concentration of ions in the cell sap also increases the concentration of the cell sap in the root hair cells compared to the surrounding soil, which can lead to more endosmosis and more water being absorbed by the roots.
