Answer» Only`A` Only`B` Both `A` and `B` Both `B` and `C` Solution :The roots of some higher plants are associated with fungal mycellia. Such an association is called nycorrhiza. It REPRESENTS a mulualistic (SYMBIOTIC) association between the roots system of higher plants and fungal hyphae.The fungal hyphae form a network around the YOUNG root and INVADE the root cells. The extrnal hyphae greatly increase the surface area for absorption of minerals and water from a much larger volume of SOIL that perhap the roots alone cannot do.
