Function of leghaemoglobin during biological nitrogen-fixation in root nodules of legumes is to

Options

A. convernt atmospheric `N_(2)` to `NH_(3)`
B. convert ammonia to nitrite
C. transport oxygen for activity of nitrogenase
D. protect nitrogenase from oxygen

Answer

d

Explanation

Rhuizobium is the nitrogen fixing bacteria present in root nodules of legume.s Roots of a legume secrete chemical attractangs flavonids and betaines. Bacterial collect over the root hairs, around the bacteria. Degradations of cell wall and formation of an infection thread enclosing bacteria. The dividing. It produce selling of nodules and the form irregular polyhedral structures called bacteriods. The most cells develops a pinkish coloured pigment called leg haemoglobin. It is an oxygen svavenger and protects nittogenase from oxygone. Symbiotic nitrogen requires co-operations of Nod genes of legumes. nod nif and fix genes of bacteria.
