Ectomycorrhiza is a type of symbiotic association between certain fungi and the roots of plants, particularly trees. In this relationship, the fungal hyphae envelop the root tips, forming a protective sheath. This interaction enhances nutrient and water absorption for the plant while providing the fungus with carbohydrates produced through photosynthesis. Ectomycorrhizal fungi are crucial for the health of many forest ecosystems. They help trees, such as pine and oak, thrive in nutrient-poor soils by improving access to essential minerals like nitrogen and phosphorus. This partnership supports biodiversity and contributes to soil stability and fertility.
