Hypotonic There is a higher concentration of solutes inside the cell than outside the cell. Water movesinto the cell to equal out the concentration.
Animal Cells: Most will swell and burst (lyse) due to the water moving in
Plant Cells: Cells remain in a normal "turgid" state but the vacuoles will be swollen and full.
Isotonic The inside and outside of the cell have an equal solute concentration. Water continually flows in and out to maintain the balance in a "dynamic equilibrium."
Animal Cells: The cell will be in a normal condition as it remains in homeostasis
Plant Cells: The cell will be in a normal condition. The vacuole will be full, but not swollen.
Hypertonic There is a higher concentration of solutes outside the cell than inside the cell. Water will move out of the cell to equal the concentration.
Animal Cells: The cells will shrivel due to the water loss
Plant Cells: The vacuole will lose water and the cytoplasm will shrink away from cell wall. This is called plasmolysis and will result in lower turgidity that causes the plant to wilt.
