What is the name of the fungus that forms a symbiotic relationship with plant roots? A mycorrhizal fungus.

Mycorrhizal fungi colonize plant roots and exchange nutrients with their host plants. The fungus receives carbohydrates, such as sugars or lipids, produced by the plant through photosynthesis.

In return, fungal hyphae expand the effective absorbing network around the roots. This can improve the plant’s access to water and minerals, including phosphorus, nitrogen, and zinc.

The term “mycorrhiza” properly refers to the symbiotic association between a fungus and plant roots, rather than to the fungus alone. The organism is therefore best called a mycorrhizal fungus, although “mycorrhiza” is the expected quiz term.
