Mycorrhizae are beneficial fungi that form symbiotic relationships with plant roots, helping plants absorb water and nutrients, particularly phosphorus. In exchange, the fungi receive carbohydrates produced by the plant through photosynthesis. Mycorrhizal associations enhance root systems by extending the plant's ability to access nutrients from the soil, improving plant health, and increasing resilience to drought, disease, and poor soil conditions. Mycorrhizae play a crucial role in soil ecology and plant growth.
