Did you try a series of different salt solutions, to see if the resistance went down as the salt concentration went up did you get fairly consistent resistance readings if not, what went on. It is possible to observe the plasmolysis of cells under the microscope solution of salt-water using a pipette, add one drop of this solution to the specimen . Wet solution dry solution why does my solution start to boil depending on how much water remained in the solution, the solvent can boil if too much drying agent was added at once. Wet mount technique is used for preparing eukaryotic cells, such as the cells of plants and animals for the microscope in order to view bacteria ( prokayotes ), which are much smaller than plant and animal cells, a different specimen preparation technique is used called a bacterial smear.
The right micrograph above is elodea cells in salt water, 100x note that the only difference is the increase in white areas in the salt water micrograph, due to the shrinkage of the cells also note that the view are not very informative, due to insufficient magnification. This site might help you re: why do elodea leaf cells look different after salt is added to it in science, we did an experiment with a small piece of elodea leaf we first added one drop of water, made a slide and then observed it on high power on a microscope next we added salt water in. If you add a salt solution to red onion cells what will happen we did a lab in biology but i didn't get to finish it we were observing red onion cells using a microscope.
