Answer 2

Answer:

Part x is the root nodules

Rhizobia is present in x

These symbioses result in the formation on legume roots of differentiated organs called nodules.

Explanation:

Rhizobia is a living bacteria in root nodules that help to fix nitrogen in the soil.

Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant.
