The Incredible Shrinking Potato! 🥔💧
Can you change the shape of a vegetable using nothing but water? This is Osmosis in action!
What you need:
* Two Potato slices/cylinders (keep them the same size to start).
* Cup 1: Distilled Water (Pure H_2O).
* Cup 2: Concentrated Salt Water.
The Results:
* The Turgid Potato: In distilled water, water rushes into the cells. They become stiff and swollen.
* The Plasmolyzed Potato: In salt water, water rushes out of the cells to try and balance the concentration. The potato becomes soft, limp, and "shrivelled."
The Biology Breakdown:
Water always moves from an area of high water concentration to low water concentration through a semi-permeable membrane. This is why hydration is so important for our own cells!
