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.
Mycorrhiza are roots of plants surrounded by fungal filaments. Plants supply sugars to the fungi, and the fungi provide water and nutrients to the plant by extending from the root hairs. sugar sink is a net consumer or storer of sugar. Growing roots, buds, stems, and fruits are all sugar sinks. A storage organ, such as a tuber or a bulb bay be a source or sink, depending on the season.
