Detailed explanation-1: -In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute.

Detailed explanation-2: -Water will move from the side with lower solute concentration to the side with higher solute concentration until the concentrations are equal, or until some external force prevents further movement of water. This is a passive process, in that no energy expenditure is required for the movement of water.

Detailed explanation-3: -Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. At this point, equilibrium is reached.

Detailed explanation-4: -Very simple explanation for osmosis is the concentration of water explanation-water in pure water is simply more concentrated than water in solutions because the solute has to take up some room in the solution.

Detailed explanation-5: -Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water. Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction.
