stepladder [879]

Answer: Cell number one is an hypotonic solution, cell number two is an isotonic solution, and cell three is an hypertonic solution.

Cell number two which is a 98% water content added with a 98% water solution. These two solutions are equal to one another, so the water does not move. This is isotonic.

Cell number three which is a 98% water content added with a 80% water solution. Water moves from high to low concentrations, so water moves from the cell to the solution. The water leaves the cell, which is an hypertonic.
