In lab, imagine that you are given a section of the aquatic plant, elodea, to observe. as part of your observation, you prepare a wet mount of elodea, and add a 20% nacl solution to your slide. what should you expect to see when you observe this slide through the microscope?

You are expected to see the movement of the water trhough a plasmatic membrane.  

Explanation:

When we put a cell in different solutions , whit different concentrations, we can observe modifications in the protoplasm.    When a cell it´s in the presence of a salin concentrated solution (hipertonic), the water goes out the cell trhough the plasmatic membrane and this phenomenon its called plasmolisi.
