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.
Mycorrhizae: Plant-Fungus Partners. Unlike plants, fungi cannot make their own food. They absorb their food from dead organic matter, or other living organisms. The source of their food is called a substrate if it is dead, and a host if it is living.The body (mycelium) of a fungus is made of threads called hyphae.Hyphae absorb nutrients from the substrate, spread, grow, and produce fruiting bodies.he source of their food is called a substrate if it is dead, and a host if it is living.
