Summary Introduction
Introduction: Property of water that determines the way it will flow, which depends on the concentration of solutes in water and pressure being exerted on water, is known as water potential. If the concentration of a medium surrounding the cell is higher than the inside, the cell water will move toward the cell.

An experiment is designed to study the mechanism of sucrose uptake by plant cells. Cells are immersed in a sucrose solution, and the pH of the solution is monitored. Samples of the cells are taken at intervals, and their sucrose concentration is measured. The pH is observed to decrease until it reaches a steady, slightly acidic level,and then sucrose uptake begins. (a) Evaluate these results and propose a hypothesis to explain them. (b) Predict what would happen if an inhibitor of ATP regeneration by the cell were added to the beaker once the pH was at a steady level. Explain
