A mycorrhiza (Greek: Î¼ÏÎºÏÏ, mykÃ³s, fungus, and ÏÎ¯Î¶Î±, riza, root, pl. mycorrhizae or mycorrhizas) is a symbiotic association between a fungus and the roots of a vascular host plant. The term mycorrhiza refers to the role of the fungi in the plants' rhizosphere, its root system. Mycorrhizae play important roles in soil biology and soil chemistry.
This kind of mycorrhizae is confined to the cells of the root system; causing internal infections of the cortex of root and rhizome of the plants. The most important role of the fungus of endomycorrhizae is the disintegration of soil particles and absorption and transport of released particles in to the plants. The formation of endomycorrhizae does not alter the the morphology of the root system.
