Symbiotic relationships with Nitrogen-fixing Bacteria: Rhizobium bacteria normally inhabit the soil. Suggest why nodules are found on the stems of Sesbania? The roots of the Sesbania are often underwater or in flooded soils that do not contain much N2. Bacteria live best above the ground. Sesbania only use the nitrogen in the upper portion of the plant so they do not need to make nodules on their roots. Bacteria will drown under water.

Rhizobium is important agriculturally because it supplies __________ to plants such as peas and beans. View Available Hint(s) for Part A oxygen sulfur fixed nitrogen carbon
One of the most widely known symbioses between microorganisms and plants is that of rhizobia and legumes. The basis of this mutualistic, symbiotic relationship can be described by which of the following statements? Actually, all of these are accurate descriptions of the symbiosis between rhizobia and plants. Rhizobia help the plants expand access to minerals in the soil while the plant protects the rhizobia from predators and viruses. The rhizobia will conduct photosynthesis which allow the plants to access carbon without having to deplete their own energy to do carbon fixation. The rhizobia fix nitrogen for the plant while the plant fixes carbon which it shares with the rhizobia. The rhizobia will produce oxygen which will help the soil to maintain oxygenation and thus avoid pathogens.
