Summary Introduction

To determine: Some ways that explain that the relationship between a plant root and a mycorrhizal fungus is mutualistic.

Introduction: Mycorrhiza is a symbiotic association between a fungus and the roots of a host plant. In this association, fungi colonize the host plant’s root tissues either intracellularly or extracellularly. Most plant species form mycorrhizal associations, though some families like Brassicaceae and Chenopodiaceae cannot form this association.
