Elodea with Salt Solution

Today in science we did an experiment with elodea. It was pretty cool. When the salt solution was running through the cells it looked darker and smaller. This is because plasmolysis took place. Plasmolysis is the process in plant cells where the membrane pulls away from the cell wall due to the loss of water through osmosis.So basically it's when the water in the cell leaves so the organals clump together.
