One way substances can get into a cell is called passive transport. One special kind of passive transport is osmosis, when water crosses into the cell. This experiment allows you to see the process of osmosis in action. Are you ready?

Can you go into greater detail about how and why this happened?
This is a follow up experiment to the main topic we covered in Cells. Find the science concepts explained in detail under LIVE CLASSES -> Feb Biology -> Cells (week 26). I hope this is helpful!
If you take a ruler and measure the largest diameter of the potato (because it’s not perfectly circular), and compare your results to the diameter after, you’ll see a difference of a few milimeters.
The video does not explain how you know that the potato in salt expanded and how you know that the potato in plain water didn’t shrink.
