Answer 1

Mycorrhiza is a mutual association of fungal hyphae with the roots of higher plants.

Mycorrhiza is a mutualistic (symbiotic) association between fungal hyphae and the roots of higher plants. The fungus helps the plant in better absorption of water and minerals (especially phosphorus), while the plant supplies the fungus with sugars and other organic nutrients.
