Accepted Answer

Hello everyone and welcome to today's video. So we have that there are several benefits to plant roots being associated with micro rizzo fungus. Except for. So which of these following answer choices does not represent one of these benefits that the question is asking for. Well before we jump into this problem, I really want to help you recall some of the benefits that these micro rise of fungus provide for plants. And here we have them. These are fun guys that are going to provide, first of all a physical barrier to the plant in the roots while helping the plan absorb certain nutrients. So this is how the symbiosis is going to work. Now that we know this. Let's go over answer choices so that we may solve the problem. Beginning by answer choice A We have here resistance to born pathogens. Well, since these fungi are going to be providing a physical barrier to plant, this is going to be one of these benefits are going this physical barrier is going to increase the plant's resistance to these pathogens. So we're going to cancel this out because this is a benefit. Then we have both increase in plant growth and development an increase in mineral absorption. Well, these fungi are also helping the plant absorb nutrients. And this is going to increase the mineral absorption of the plan. And it's also going to help in its development and its plant growth because these nutrients are going to go into helping the plan develop. So both of these answer choices actually represent some of the benefits that these fungi provide for the plants. So we're going to cancel the mod as well. Then we have answer choice convert atmospheric nitrogen into a form usable by plants is actually going to be an incorrect answer choice because this is not provided by fungi is provided by a specific type of bacteria called Rise oh Beom. This is not going to be provided by the fungi in the question, so this is the incorrect answer choice or the answer choice. That does not represent a benefit that the fungi provide for the plans. We're going to highlight answer choice E as the correct answer to our question. I really hope this video helps you and I hope to see you on the next one.
