What is symbiosis, fungus root or mycorrhiza, what is the relationship between them?

Mushrooms are a separate kingdom that has existed for more than one century. They are universal, as in some ways they are similar to plants or animals. That is why they can cooperate with both representatives. This connection is called symbiosis – organisms of different types exist together, complement and fill each other with the necessary minerals and trace elements.
Mycorrhiza (fungus root) is a way of existence of a fungus and a plant. In this case, the non-pathogenic spores of the former enter the soil and form a single whole with the roots of the latter. The hyphae of the fungus entwine the roots of the tree, and mycorrhiza forms. Now they live together, exchange nutrients. This relationship was discovered in 1885 by Albert Frank.
