Mycorrhiza represents

Mycorrhiza (mykes = mushroom + rhiza = root) represents a symbiotic association of fungi with thhe roots of higher plant. Mycorrhiza meaning fungus root is an infected root system arising from the rootlets of a seed plant. In ectomycorrhiza, the ultimate absorbing rootlets of the root system are completely surrounded by a distinct mantle or sheath of fungal tissue. In endomycorrhiza, there is no such sheath. Most of the fungus is within the root and may be intracellular as well as intercellular.
