What name is given to the bacteria found in the root nodules of Pea plant? State their importance.

The bacteria found in the root nodules of Pea plant is Rhizobium. These bacteria are found in the root nodules of most of the leguminous plants. They trap the nitrogen from the atmosphere and convert it into nitrates (mineral salts) which can be easily absorbed by the plants from the soil along with the water. The Rhizobium bacteria lives in symbiotic relationship with the leguminous plants as the plant provides shelter to the bacteria and the bacteria provides nitrogen to the plant.
