Question

Relation between bacteria and legume having modulated rootes

Answer 1

There are some bacteria called rhizobium which fix nitrogen in the soil ,not only rhizobium there are some more like clostridium and azetobacter ,they fix nitrogen in the soil . The relation of these bacteria and leguminous plant is that they live in roots of these leguminous plants.

Answer 2

There is a symbiotic relationship between bacteria and leguminous plants. In this symbiotic relationship, the bacterium called Rhizobium converts the atmospheric nitrogen into a soluble form which the plants can absorb as they cannot absorb atmospheric nitrogen directly. The nitrogen helps the plants in their growth. The plants, in turn, provide food and shelter to the Rhizobium.
