How do mycorrhizal fungi benefit plants? (Site 1)

short paragraph

Answer 1

Mycorrhizal fungi form a symbiotic relationship with plant roots in which the fungi’s fine hyphae extend far into the soil and greatly increase the root system’s surface area. This expanded network improves the plant’s uptake of water and essential nutrients—especially phosphorus and sometimes nitrogen—and can also help plants tolerate drought, salinity, and certain soil-borne pathogens. In return, the plant supplies the fungi with carbohydrates produced by photosynthesis, making the partnership mutually beneficial and often resulting in healthier, faster-growing plants.
