10. What is the role of the bacteria in leguminous plants?

A. Convert oxides of nitrogen into soil nitrates.
B. Convert atmospheric nitrogen gas into soil nitrates.
C. Convert soil nitrates into gaseous nitrogen.
D. Convert plant proteins into ammonia.

11. Conduction of inorganic materials in plants occurs mainly through which pathway?

A. Xylem
B. Phloem
C. Sieve tube
D. None

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.
