Leaflets of Mimosa pudica (common names: sensitive plant, touch-me-not) have a remarkable ability to close up in response to being touched or physically moved. How fast can the leaflets close? How does this occur? And more importantly, what benefit could this unusual response provide to the plant? If just the leaflets located toward the end of a leaf are touched, the adjacent leaflets close in fairly rapid succession until all leaflets on a leaf close up. Explain how electrical signaling may be involved in this response.

Hello everyone and welcome to today's video. So which of the following is the key side of mechanized sensation in the mimosas leaflets. So let's go over answer choices so that we can understand the function of each structure. Beginning by answer choice A which is P. T. O. S. And the P. T. O. S. A lot of twisting of the plant leaves when they're exposed to light. So they're more involved with photo sensation or the sensation of light and we're going to cancel this out. Then we have pena and they provide support because they provide support. They're not going to be involved in bank on a sensation. And we're also going to cancel this up. Then we have the rashes and these rashes is the access of the compound structure of the leaves from where new branches are going to come out. This is not going to be helping in mechanized sensations were going to cancel this out. Finally, we have the pull vanilla and the pull vanilla. One of the very important functions that it has is that for example, closest these mimosa live lead one exposed to touch because it is going to close or it's going to provide an action for this mimosa leaflet. When touch is involved, it is definitely going to be involved in this mechanized sensation aspects. We're going to highlight answer choice e as a final answer to the question. I really hope this video helped you and I hope to see you on the next one
