Hello, everyone and welcome to today's video. So which of the following statement is not true about licking? Remember that we're looking for the not true or the incorrect statement and on our answer choices. So before we jump into the problem, I want should recall some very important facts about licking so that we can use it to solve it. Well, lickin is a very tough and very rigid organic polymer that is found in the xylem and the flow in plants. Now let's use this information to solve the problem beginning by answer choice B it is an organic polymer that gives us strength to supporting tissues. Here we have just this. So we're going to cancel this out because it is a correct answer choice and we're looking for the incorrect one. Then we have it causes the thickening in the primary and secondary walls of plant cells. Here we have that because they're so tough and so rigid and they provide support, they're going to cause the thickening in the primary and secondary walls of these plant cells. This is a correct statement. So we're going to cancel it out. Then we have it is found in the cell walls of vascular tissues like the xylem and the flow, which is just what we have in the definition that I provided to you. At the beginning of the video because of this, we're going to cancel this out and we have answer choice eight, it forms a waxy layer called the coal that prevents water loss. So something very important that we need to understand about the coal is that it is created by a lipid and this lipid is called cut. The critic is not formed by Lenin. So this is going to be our incorrect statement or the not true statement that the question is asking for and we will highlight it as a final answer to our question. I really hope this helped you and I hope to see you on the next one.
