Where do Rhizobium bacteria live?

Rhizobium bacteria are a type of soil bacteria that live in the soil in close proximity to the roots of leguminous plants such as peas, beans, lentils, alfalfa, and clover.

What is their function?

Rhizobium bacteria have a mutualistic relationship with leguminous plants. They form nodules on the roots of these plants and fix atmospheric nitrogen, which is converted into ammonia and other nitrogen compounds that are essential for plant growth. In return, the plant provides the bacteria with a source of energy in the form of carbohydrates.

Explain in details.

Rhizobium bacteria are able to fix atmospheric nitrogen, which is not available to most plants, into organic forms that plants can use. The process of nitrogen fixation occurs in the nodules that form on the roots of leguminous plants. The bacteria enter the plant through root hairs and migrate to the root cortex, where they multiply and form nodules.

The nodules provide a specialized environment for the bacteria to carry out nitrogen fixation. The bacteria are able to convert atmospheric nitrogen into ammonia, which is then converted into other nitrogen compounds such as nitrate and amino acids. These compounds are essential for plant growth and are used by the plant to synthesize proteins, nucleic acids, and other important molecules.

The relationship between Rhizobium bacteria and leguminous plants is mutualistic, meaning that both the plant and the bacteria benefit from the relationship. The plant provides the bacteria with a source of energy in the form of carbohydrates. The bacteria use this energy to carry out nitrogen fixation and other metabolic processes. In return, the plant receives a source of nitrogen that is essential for growth and development.

In conclusion, Rhizobium bacteria are important soil bacteria that have a mutualistic relationship with leguminous plants. They are able to fix atmospheric nitrogen, which is essential for plant growth, in specialized nodules that form on the roots of these plants. The relationship between the bacteria and the plant is beneficial to both parties, as the plant provides the bacteria with energy and the bacteria provide the plant with nitrogen.

Rhizobium is a type of bacterium that converts the nitrogen gas into usable form to be used by plants which grows in a soil less nitrogenous. Rhizobium survives in the nodules of leguminous plants and is a part of symbiotic relationship.
