Explanation

Mycorrhiza is a symbiotic association between fungi and plant roots. The fungi help plants absorb nutrients (especially phosphorus) from soil, while receiving carbohydrates from the plant. This mutualistic relationship is crucial for most terrestrial plants. Bacteria-root associations would be called rhizobia, not mycorrhiza.
