Question

During absorption of water by roots, the water potential of cell sap is lower than that of _______________

• A. Pure water and soil solution
• B. Neither water, nor soil solution
• C. Pure water, but higher than that of soil solution
• D. Soil solution, but higher than that of pure water

Answer 1

Answer:

A. Pure water and soil solution

During absorption, water moves from soil to the root which means the water potential of cell sap of root is lower than that of soil. Thus, the cell sap will have a water potential lower than the pure water and soil solution during absorption.
