Detailed explanation-1: -An isotonic solution has the same solute concentration compared to the intracellular solute concentration. When a red blood cell is placed in an isotonic solution, there will be no net movement of water.

Detailed explanation-2: -If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

Detailed explanation-3: -If a cell is placed in an isotonic solution, the water potential and will be equal inside and outside of the cell.

Detailed explanation-4: -Cell shape and size remain the same when the solution outside is isotonic. The cell shrinks and loses shape when the solution outside is hypertonic.

Detailed explanation-5: -Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic.
