Final answer:

Nitrogen-fixing bacteria in leguminous plants convert nitrogen gas into soil nitrates, while xylem transports inorganic materials from roots to leaves.


Explanation:

Nitrogen-fixing bacteria play a vital role in leguminous plants by converting atmospheric nitrogen gas (N₂) into soil nitrates, aiding in the plant's nitrogen nutrition. This process occurs in the root nodules of legumes through a symbiotic relationship.

Moreover, xylem is responsible for conducting inorganic materials in plants, such as minerals absorbed by roots, to the leaves for essential functions like photosynthesis and metabolic processes.
