Explanation:

Some sugarcane varieties are known to be capable of fixing atmospheric nitrogen in association with a bacterium called Glucoacetobacter diazotrophicus. But, contrary to legumes and other nitrogen fixing plants which form root nodules in the soil in association with bacteria, G. diazotrophicus lives within the intercellular spaces of the sugarcane’s stem.
