Answer

Legumes are able to form symbioses with soil bacteria to create a primary nodule meristem. Bacteria enter, differentiating into bacteroids that help the plant by fixing nitrogen. This mutualism is analogous to mycorrhizal associations because both symbiosis involve a microorganism living within a plant to enhance its growth and survival.
