A biologist working with cultured cells puts distilled water on the cells instead of serum (a portion of blood plasma). When she looks for the cells under the light microscope, all she sees is cell debris. What happened to the cultured cells? Make sure to mention hypertonic regions, hypotonic regions, and direction of water movement and draw a picture of the process.
