GENERAL HISTOLOGY

Detailed explanation-1: -Transferring the swollen red blood cells into a 5% solution (which is hypertonic) will drive the water molecules from the cells causing them to shrink. To allow the red blood cells to sustain their shape and vitality they should be placed in the isotonic solution (0.9% NaCl).

Detailed explanation-2: -The salt water is a hypertonic solution, thus water will move out of the cell. As water moves out of the cells there is a loss of turgor pressure and the plasma membranes detach from the cell walls as the cells shrink.

Detailed explanation-3: -Final answer: When the cell when it is placed in salt solution, it will shrinks.

Detailed explanation-4: -For example, a solution containing 10% salt is hypertonic. When a cell is placed in a hypertonic environment, there is a net movement of water to the outside of the cell (from the higher water environment inside the cell). The cell shrinks in response.
