Question

Why does rhizobium grow only on the roots of  leguminous plants but not on others?

Answer 1

HEY!!

___________________________

⚫Rhizobium live freely in soil and in the root region of both leguminous and non-leguminous plants.

⚫However, they can enter into symbiosis only with leguminous plants, by infecting their roots and forming nodules on them.

⚫Rhizobium live freely in soil and in the root region of both leguminous and non-leguminous plants.

⚫The biology of the roots in legumes aids nodule formation.

Answer 2

Hey mate!

Here's your answer!!

◾️The rhizobium fixes the atmospheric nitrogen gas in the root nodules of legumes.the atmospheric nitrogen is converted into ammonia ,which is then used in the formation of amino acids and nucleotides. Like that legumes are act as a host which serves nutrient for their growth.

◾️This mutual interaction is known as symbiotic relationship.

◾️Legumes have a symbiotic relationship with bacteria called Rhizobia, which create ammonia from atmospheric nitrogen and help the plant. The plants other than legumes don’t have a sybiotic relationship with these bacteria.

◾️Therefore, rhizobium grows only on the roots of leguminous plants but not other plants.
