Question

Which of the following statement is correct for absorption of water from root hairs?

• A. Concentration of outer environment is more than cell sap
• B. Concentration of cell sap is more than outer environment
• C. Concentration of outer environment is equal to the cell sap
• D. None of the above

Answer 1

The correct option is B Concentration of cell sap is more than outer environment

Roots have numerous root hairs that increase the surface area for the absorption of water and minerals. These root hairs are in contact with the water present in the soil. Water enters the cells of the root hair by the process of osmosis. Osmosis is the movement of water from a region of low solute concentration of outer environment to a region of high solute concentration present in cell sap.

So, the correct option is 'Concentration of cell sap is more than outer environment'.
