BIOLOGICAL DIVERSITY FUNGI Estrella Mountain Community

Mycorrhizae are fungi (usually a zygomycete or basidiomycete) symbiotic with the roots of plants. Both relationships are mutualistic both parties benefit. Fungi provide nutrients from the substrate, the phototroph provides food. Plants with mycorrhizae grow better the plant gets nutrients from the fungus in exchange for carbohydrates.
