Which root adaptation enables plants to access atmospheric nitrogen?

Question

Quizplus · Accepted Answer

Root nodules that are colonized by bacteria, such as Rhizobium, are able to fix nitrogen from the atmosphere into a form that the plant can use. This process is called nitrogen fixation and it enables plants to access atmospheric nitrogen. The nitrogen-fixing bacteria live within these root nodules in a mutualistic relationship with the plant where the bacteria provide the plant with nitrogen and the plant provides the bacteria with carbohydrates produced during photosynthesis.
