Hypotonic high concentration of water outside of the cell
10/15/2019 Hypotonic high concentration of water outside of the cell Movement of water into the cell Cell swells Distilled water Pond water for most organisms must have contractile vacuole Cytolysis – bursting of cells
7
Hypertonic High concentration of water inside the cell
10/15/2019 Hypertonic High concentration of water inside the cell Water moves out of the cell Cell shrinks (plasmolysis) Salt water
8
Isotonic Same concentration inside and outside the cell
10/15/2019 Isotonic Same concentration inside and outside the cell No net movement of water no affect on the cell Blood plasma Why?
