In case of osmosis if the concentration of the surrounding solution is the same as that inside the cell, in which direction will the net movement of water molecules be across the cell membrane?

Solution
An Isotonic solution is a solution that has the same concentration of dissolved substances as is found inside the cell. If a cell is surrounded by isotonic solution, then there is no net movement of water across the membrane by osmosis, because the concentration of water is the same on both sides of the membrane
a. Osmotic pressure is the external pressure required to be applied so that there is no net movement of solvent across the membrane.
b. Reverse Osmosis is a process where you demineralize or deionize water by pushing it under pressure through a semi-permeable Reverse Osmosis Membrane.
c. In Osmosis when equilibrium is reached, then water stops flowing across the membrane
