Sagot :
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. ... Legume crops include beans, peas, and soybeans.
Answer:Root nodule symbiosis enables nitrogen‐fixing bacteria to convert atmospheric nitrogen into a form that is directly available for plant growth. Biological nitrogen fixation provides a built‐in supply of nitrogen fertiliser for many legume crops such as peas, beans and clover.
