OK, not quite that kind of cell.
This post is about plant cells! Do you know why plants droop when they need water? It is because the cells do not have water in them. Turgor pressure is a force within plant cells that pushes the plasma membrane against the cell wall making the plants perky.
So, the next time you hear mom says “looks like the plants need a drink” explain to her why!
We thought it would be fun to simulate turgor pressure using audio. In the simulator below, we coded the plant to respond to voice. The louder you scream at it, the happier it becomes, just like adding water to soil. Here is our Scratch code:
Feel free to scream now on the project page!
