Nitrogen- fixing micro-organisms in leguminous plants live symbiotically in the
Nitrogen-fixing microorganisms live in a special structure called root nodules that form on the roots of leguminous plants. These microorganisms, called rhizobia, have the ability to convert atmospheric nitrogen into a form that plants can use to grow. This process, called nitrogen fixation, is essential for plant growth because nitrogen is a crucial component of many important molecules, such as DNA and proteins. In exchange for fixing nitrogen, the rhizobia receive carbohydrates and other nutrients from the plant. This symbiotic relationship between leguminous plants and nitrogen-fixing microorganisms is important for the health of the plant and the surrounding ecosystem.
