Question

In a mycorhizal symbiosis, the microbial symbiont does which of the following processes for its host?

Group of answer choices

nitrogen fixation

absorption of water and inorganic nutrients

chemolithoautotrophy

produces light

digests cellulose

Answer 1

Answer is option 2

Mycorhizal symbiosis is the close association between root of plant and fungus. The plant provides organic food to the fungus which formed by plant during the process of photosynthesis.

And the fungus provides Or help to the plants for absorption of water and inorganic nutrients by increasing surface area of root. Fungi make mycelium which dispersed over long distance. These mycelium receives water and nutrients from far away and provides to the plant or host.

For additional knowledge

Fungus individually doesn't fix nitrogen for plant or host. Fungi with some bacteria collectively fix the nitrogen for their host.
