Root fungus. Light micrograph of a cross-section through a root containing fungal hyphae called endotrophic mycorrhiza. The hyphae (green and blue) are in the inter-cellular spaces and inside some cells. The hyphae extend into the soil and pass mineral salts and water up to the root, so it no longer needs the hairs that normally serve this function. The plant supplies the fungus with sugars and other organic substances, enabling a mutually beneficial (symbiotic) relationship. Magnification: x100 when printed 10 centimetres wide.
