Question

Which Saline concentration would result in cell shrinking (0%, 0.9%, 10%) and why? Make sure you explain using Osmosis.

Answer 1

10%

Well, the cell has been placed in a concentrated solution which means the water content inside the cell will be higher than outsider the cell. Osmosis is the movement of water molecules from an area is of high concentration to low concentration down the concentration gradient. So, through the process of osmosis, water will leave the cell and go into the solution.
