English: Mycorrhizal fungi are in a symbiotic relationship with plants. The relationship is usually mutualistic, the fungus providing the plant with water and minerals from the soil and the plants providing the fungus with photosynthesis products. Some fungi are however parasitic, taking products from the plant without providing benefits. Conversely, some mixotrophic or parasitic plants connect with mycorrhizal fungi as a way to obtain photosynthesis products from other plants. Finally, saprotrophic (or saprophytic) fungi live on dead organic matter without establishing a symbiosis with plants.
