Question

what will happen if cell sap of root hair cells contain high concentration of ions

Answer 1

It will get highly concentrated
as the movement of water through the root hairs occurs with the movement of ions as there are ions present this causes repulsion and ions will not move and thus water will not move and hence the water present in the cell sap will get less and less

Answer 2

Answer :

a. The cell membrane of root hair is a semi-permeable membrane.

b. It allows the movement of water from its higher concentration (in soil water) molecules to its low concentration (as in cell sap) as in this case.

c. The root hair cells contain a high concentration of ions and salts as compared to soil water. As a result, soil water will move into the cell sap of root hairs.
