Expert Answer:

Mycorrhiza is a symbiotic association of a fungus with the roots of higher plants. The fungus absorbs water and phosphates from the soil and passes it to the plant. It solubilises complex organic matter into simpler substances. It also provides resistance to root-borne pathogens and increases the tolerance of plant to salinity and drought. In this way, the mycorrhizae act as effective biofertilisers. The most common fungi that form mycorrhizal association with plants are Glomus species.
