Root nodules are swollen structures present present in roots of leguminous plant which belong to family Fabaceae e.g. Pisum sativum , Medicago , Arachis . This family is the second largest family of Dicots and second most important family from economic point of view.These root nodules are formed by Bacteria named Rhizobium. These Bacteria are nitrogen fixing bacteria i.e. they trap N2 from air and convert it into NO3 which is used as fertilizer by plants. There is symbiotic relation between legume roots and N2 fixing Bacteria .They increase soil fertility .

Where do most Nitrogen Fixation bacteria live?
Legumes have nirtifying bacteria in their roots, but mostly they are found in the soil.
How do root nodules form?
Leguminous plants like pea and soya bean have the nitrogen fixing bacteria Rhizobium in their root nodules. The nitrogen fixed by this bacteria are taken up by herbivores which eat the palnts and then to carnivores which eat herbivores.
Nitrogen fixing bacteria live symbiotically in what?
they live in the roots of beans and peanuts- jeff chandler
What do root nodules help the plant obtain?
Root nodules contain nitrogen fixing bacteria which help a plant to obtain nitrogen compounds, which are needed for the production of protein (and although plants do not contain as much protein as animals do, they still need a certain amount of it).
Bacteria in root nodules change nitrogen gas into what form?
ammonia
What is found in the root nodules of leguminous plants?
it is rhizobium
How are root nodules useful for the plants?
The root nodules of leguminous plants like gram,pulses,etc. contain nitrogen-fixing bacteria,rhizobia, which help in fixing nitrogen in the soil for the plants to absorb.Nitrogen is essential for the growth of plants.
The knoblike root nodules of soybean plants are the sites of?
nitrogen fixation
Where are nitrogen fixing bacteria found on plants?
The root nodules. they fix the bacteria in the soil so it's the most sensible place!
Where do most Nitrogen Fixation bacteria live?
Legumes have nirtifying bacteria in their roots, but mostly they are found in the soil.
What is a plant swelling?
Plant parts are swollen in many cases due to storage of food. In some aquatic plants, some plant parts like leaf petiole are swollen due to air chambers so that these plants can float in water.
The function of the root nodules of legumes is storage of carbohydrates?
its the nutrients in the plants OJ :)poop
Why legiminous plants have root nodules?
It contains bacteria that fix nitrogen in the soil. This provides this vital element not only for the legume but also other plants in the vicinity
Are there any root nodules harbor in nitrogen fixing bacteria?
yes,there are root nodules
How is nitrogen fixed in the soil?
Bacteria that exist in the root nodules of some plants can absorb nitrogen from the air in the soil. One notable example is the Rhizobia that lives in nodules on soybean roots. Similar root systems exist in clover and alfalfa.
Where do you find root nodules?
Root nodules with bacteria are found fairly easily on legumes like beans, peas, clover, soy and peanut as well as on alder trees. Some plants have scarce nodule development and others have dense clusters.
