Question

how are root nodules on the roots of leguminous plants useful for the crop ​

Answer 1

Answer:

Root nodules are found on the roots of plants, primarily legumes, that form a symbiosis with nitrogen-fixing bacteria. Under nitrogen-limiting conditions, capable plants form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia. ... Nitrogen fixation in the nodule is very oxygen sensitive.

Answer 2

Answer:

$\huge\mathbb\red {Answer}$

Many legumes have root nodules that provide a home for symbiotic nitrogen-fixing bacteria called rhizobia. This relationship is particularly common in nitrogen-limited conditions. The Rhizobia convert nitrogen gas from the atmosphere into ammonia, which is then used in the formation of amino acids and nucleotides .
