What is mycorrhiza?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
A mycorrhiza is a symbiotic association between a fungus and the root system of a higher plant. This mutualistic relationship benefits both organisms: the fungus receives organic nutrients (sugars) from the plant, while the plant gains enhanced absorption of water and minerals (especially phosphorus) through the extensive fungal hyphae network. Mycorrhizae are classified into ectomycorrhizae and endomycorrhizae based on the location of fungal colonization.
Key Point: Plants like Pinus cannot germinate without mycorrhizal association, highlighting the ecological importance of this symbiosis.
