ahriglt. So I'm going to go ahead and tap the leaf here, and I want you to look at the eirlectcal rcrinoedg that we're going to see inside the plant. Whoa. It is so big, I've got to scale it down. Alright. So what is that? That is an atcion potential that is happening inside the plant. Why was it happening? Because it wanted to move. Right? And so when I hit the touch receptors, it sent a voltage all the way down to the end of the stem, which caused it to move. And now, in our arms, we would move our muscles, but the plant doesn't have muscles. What it has is water inside the clles and when the voltage hits it, it opens up, releases the water, changes the shpae of the cells, and the leaf falls.

Alright. So I'm going to go ahead and tap the leaf here, and I want you to look at the electrical recording that we're going to see inside the plant. Whoa. It is so big, I've got to scale it down. Alright. So what is that? That is an action potential that is happening inside the plant. Why was it happening? Because it wanted to move. Right? And so when I hit the touch receptors, it sent a voltage all the way down to the end of the stem, which caused it to move. And now, in our arms, we would move our muscles, but the plant doesn't have muscles. What it has is water inside the cells and when the voltage hits it, it opens up, releases the water, changes the shape of the cells, and the leaf falls.
