Detailed explanation-1: -If the concentration of solution inside the cell and outside the cell is same, there will be no net movement of water molecules. Such type of solution is called isotonic.

Detailed explanation-2: -If the percent concentration is equal both inside and outside a cell, water does not move into or out of the cell. If the percent concentration is greater in the fluid inside a cell than outside a cell, water will flow into the cell.

Detailed explanation-3: -If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.

Detailed explanation-4: -When placed in a solution of 30℅ water 70℅ the cell will shrunken. This is happened because of exo osmosis. Exo osmosis is actually the flow of water to outside the cells when it is placed in a hypertonic solution.

Detailed explanation-5: -If a cell is hypertonic, it has a higher concentration than the solution does, meaning water will flow into the cell. If the cell is hypotonic, this means that it has a lower concentration than the solution, and water will flow out of the cell and into the more concentrated solution.
