If it were possible to increase nitrogen transport from rhizobia in root nodules to any
part of soybean plants, what implications would this have for agriculture and food?
Soil microorganisms, collectively referred to as dizotrophs, fix 90% of the inert nitrogen gas to
ammonium and nitrate. There are two-main types of nitrogen-fixing bacteria: free-living (nonsymbiotic)
and mutualistic (symbiotic). Describe the mutualistic relationship between Rhizobium and legumes. What
is the advantage of using legumes as a cover crop in agricultural systems?
A point of interest is that the nitrogenase enzyme complex is highly sensitive to oxygen. This is a major
problem for free-living aerobic species such as cyanobacteria and species of the genera Azotobacter and
Beiigrinckia. Describe two ways the bacteria can overcome to levels of oxygen in their cells.
Why is nitrogen fixation so energetically costly?

- During biological nitrogen fixation, microbial plant symbionts uptake_________and converted it to__________?arrow_forwardWhich of the following explains why pea plants in high soil nitrogen conditions have so few rhizobial nodules on their roots? When there is already high soil nitrogen there is a very large cost to having rhizobial nodules. The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the soil, so when there is already high soil nitrogen there is no advantage for the pea plant to expend the extra energy housing the rhizobia. The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia to keep the nitrogen for itself. When there is already high soil nitrogen there is no benefit to the plant to having rhizobial nodules, which can rob the plant of the high nitrogen supplies so that the rhizobia bacteria do not have to fix the nitrogen themselves.arrow_forwardExplain the consequences to the nitrogen gas in the atmosphere if all the nitrogen- fixation prokrayotes would die suddenly.arrow_forward
