How do mycorrhizal fungi help trees get nutrients from the soil?
Quick Answer
Mycorrhizal fungi extend a tree’s root system with fine threads called hyphae. In return for sugars from the tree, the fungi help absorb water and minerals, especially phosphorus and nitrogen.
The Full Story
Mycorrhizal fungi form partnerships with plant roots, and this relationship is one of the most important in terrestrial ecosystems. The fungal hyphae grow far beyond the root surface, greatly increasing the area available for absorbing nutrients and water. In exchange, the tree supplies the fungi with carbohydrates made through photosynthesis. This symbiosis is especially valuable in poor soils, where phosphorus and nitrogen can be limiting.
