Question 24 In a mycorrhizal relationship, what benefit does the fungus get from the plant? a. increased parasitic opportunities b.access to organic compounds c. cycling of nutrients back to the soil d. aid in the absorption of water and minerals e. it's actually a commensal relationship

Answer 1

It is a relationship where the mycorrhizal fungus lives in the roots of plants. In this case both the plant as well the fungus help each other to sustain their life.

Here the question asked what is the benefit the fungus got from the plant?

Plant produces sugar through the help of sunlight and water. As these fungus lives in the root of the plants, they help to aid the absorption of water and minerals and by return got the necessary nutrient to sustain its life. So it is a clear example of symbiotic mutualism.

Hence both the plants and fungus help each other and it is symbiotic, there will be no possibility for parasitic opportunity.

The microzial fungi fixed the athmospheric nitrogen in the soil and also after the death of plant it releases the esential nutrient back to the soil. But it is not the benefit the fungus gets from the plant. It is one of the work of the fungus.

The microzial fungi help to increase the mineral and water intake by the plants . Hence it is the benefit which the plant gets from the fungi.

In return , plant provides the fungus with essential sugars , nutrients . It means the fungi get access to the organic compound from plant. This is the benefit that the fungus gets from the plant.

Hence the right answer is -' Access to Organic compounds.
