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 .

Why legiminous plants have root nodules?

Leguminous plants have root nodules because they form a symbiotic relationship with nitrogen-fixing bacteria, usually of the genus Rhizobium, that reside within these nodules. The bacteria convert atmospheric nitrogen into a form that the plant can use for growth, providing the plant with a vital source of nitrogen while the bacteria receive nutrients from the plant.


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.


Where do most Nitrogen Fixation bacteria live?

Legumes have nirtifying bacteria in their roots, but mostly they are found in the soil.


Where are nitrogen fixing bacteria found on plants?

Nitrogen-fixing bacteria are commonly found in nodules on the roots of leguminous plants, such as soybeans, peas, and clover. These bacteria form a symbiotic relationship with the plant, providing it with usable nitrogen in exchange for sugars produced through photosynthesis.


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).


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.
