Hello, everyone. I hope all is well. And today I will be helping you with the fourth problem of the chapter 26 problems. And what this question is asking is what hormone closes the store Mata underwater stress. So I would do this by prom. And first off, how this tomato open a close is due to potassium ions and, um, calcium ions as well, but significantly the potassium on. So when the stomach open, potassium ions will go into the cell, which will make a target. Therefore, it'll open. And then when the stomach clothes, the potassium minds will go outside, which will make the guard sells a limp and then the stomach clothes. So out of purchase problem by process of elimination. And one of the key things is knowing all the traits of these. So we know that oxen helps with the growth of the roots. So, um, the growth of the roots really have nothing to do with the cartels opening and closing so we can get rid of that one, and then we have ah gee Berlin's, which are usually dealt with with stem elongation. And so the allegation does not necessarily have anything to do with still motto opening, closing so we can cross that one off as well. And then we have Sardo commends, which are dealt with deal with cell division and everything of that such So we know that cell division has nothing to do with the stone opening it closing because it's about the guards, is being targeted and limp, and that's the difference between them and the water pressure. So no F. Lane. The thing about Kathleen and is that it deals with the ripening of the fruit so that nothing really to pertain to the guards owes opening and closing. But of cystic acid. Actually does, um, make the stomach open and close because it initiates and maintains seed and but a dormancy. So, really, when sta mata are opening and closing, it's really helping the plant grow and develop certain things because it needs certain nutrients to in order to survive. So the answer is E. So I hope you found this video very hopeful, and I hope you have a great day
