Question

Explain the symbiotic association between the leguminous plant and rhizobium​

Answer 1

Answer:

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

Explanation:

1. Rhizobium is the bacteria that live in symbiotic association with the root nodules of the leguminous plants. Fixation of nitrogen cannot be done independently. That is why rhizobium requires a plant host.
2. Rhizobium is a vital source of nitrogen to agricultural soils including those in arid regions.
3. They convert dinitrogen into ammonia. Ammonia, being toxic in nature. is rapidly absorbed into organic compounds.
4. Rhizobium is a bacterium found in soil that helps in fixing nitrogen in leguminous plants. It attaches to the roots of the leguminous plant and produces nodules. These nodules fix atmospheric nitrogen and convert it into ammonia that can be used by the plant for its growth and development.
