Soyabean transport ureides from root nodules to various plant parts as fixed nitrogen, which
Options
- Ais a nitrogen and phosphourus rich compounds
- Bcarries high N O 3 than carbohydrates
- Ccarries high N : C ratio
- DIs highly soluble in organic compounds so, transported through xylem.
Correct answer
C. carries high N : C ratio
Step-by-step solution
Atmospheric nitrogen can be accessed by the nitrogen-fixing bacteria that are found root nodules of Soyabean plant. The plant and bacteria are in a symbiotic relationship where the pant provides shelter to the bacteria and in return microbe provides fixed nitrogen. The ureides allantoin and allantoic acid are products of nitrogen fixation process and are the dominant long-distance transport form that are carried from nodules to the different parts of plant. Since amides contain more nitrogen than the amino acids, t
