Question

Which group of soil microorganisms, forming a symbiotic association with the roots of the majority of cultivated plant species, extends the effective root surface area through fine fungal hyphae, thereby significantly improving the plant's uptake of relatively immobile nutrients such as phosphorus, as well as water?

Mycorrhizal fungi form a symbiotic association with the roots of the majority of cultivated plant species, extending the effective root surface area through fine fungal hyphae that penetrate a much larger volume of soil than the plants own roots, thereby significantly improving uptake of relatively immobile nutrients such as phosphorus, as well as water.
