A small pine tree grown in a glass box shows the intricate network of white, finely branched mycorrhizal threads or “mycelium” that attach to roots and feed the plant.

These mycorrhizal fungi form symbiotic relationships with plants, helpng them absorb water and nutrients from the soil while receiving sugars and other compounds in return.

This incredible underground network supports plant health and growth, illustrating the vital conections within ecosystems. 🌱
