Detailed explanation-1: -Leguminous plants have symbiotic relation with the Rhizobium bacteria found in the root nodules of these plants. These plants have the ability to fix atmospheric nitrogen in their roots with the help of these bacteria.

Detailed explanation-2: -Nitrogen fixing bacteria are present on root nodules of leguminous plants to fix nitrogen.

Detailed explanation-3: -Rhizobium attaches to the roots of the leguminous plants resulting in the generation of root nodules. It forms a symbiotic association with the leguminous plants as it draws the nutrition from the plants and in turn helps with the fixation of nitrogen in the soil for the leguminous plants to take up.

Detailed explanation-4: -The root nodules in leguminous plants are actually home to many nitrogen fixing bacteria like Rhizobium. They are usually be seen in nitrogen limited conditions. Example: Leguminous plants like beans, clover, peas. A symbiotic relationship between the plant and the bacteria is the seen in the root nodules.

Detailed explanation-5: -Rhizobia are Gram-negative bacteria (Proteobacteria) that reside in the root nodules of leguminous plants and are known for their ability to fix nitrogen for legume hosts in exchange for carbon.
