ammonia
Nitrogen-fixing bacteria are primarily responsible for converting atmospheric nitrogen into a useable form, such as ammonia, that can then be utilized by plants for growth and development. These bacteria are found in the root nodules of leguminous plants, where they form a symbiotic relationship with the plant.

Bacteria Ammonia, nitrates, nitrites
Generally leguminous plants i.e.,plants of Family Fabaceae have root nodules inhabited by nitrogen fixing bacteria such as Rhizobium leguminosarum,which retains and increases the nitrogen content in the soil.
Nitrogen fixation by bacteria in the soil or root nodules of leguminous plants converts atmospheric nitrogen into a form that plants can use. Decomposition of organic matter releases nitrogen back into the soil as ammonium. Application of nitrogen-containing fertilizers can supplement soil nitrogen levels for plant growth.
Nitrogen gas (N2) is converted by nitrogen-fixing bacteria that live in the root nodules of Legumes into NH3.
Bacteria in root nodules convert nitrogen gas into ammonia, which can then be used by plants to synthesize proteins and other essential molecules. This process is known as nitrogen fixation and is important for the nitrogen cycle in ecosystems.
nitrogen-fixing bacteria
Root nodules are the specialized structures in plants that serve as a home for nitrogen-fixing bacteria, such as Rhizobium species. These bacteria are able to convert atmospheric nitrogen into a form that the plant can use for growth, providing an important source of nitrogen for plant nutrition.
The relationship between plants and bacteria in root nodules is symbiotic. The plant provides the bacteria with sugars, while the bacteria, often rhizobia, convert nitrogen gas into a form that the plant can use for growth. This process, known as nitrogen fixation, benefits both the plant and the bacteria.
change nitrogen gas into ammonia
The nitrogen cycle depends on the bacteria found in the nodules of plant roots, particularly in legumes. These bacteria, such as Rhizobium, convert atmospheric nitrogen into a form that plants can use, a process known as nitrogen fixation. This symbiotic relationship enhances soil fertility and allows plants to thrive in nitrogen-poor environments.
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle. Some nitrifying bacteria lives in the roots of legumes, and do the same job.
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.
Nitrogen is supplied to the leguminous plant in the nodules found on its roots. This nitrogen-fixing process is carried out by bacteria that form a symbiotic relationship with the plant, converting nitrogen from the air into a form that the plant can use for growth.
They are plants that live with symbiotic bacteria in their roots which form nodules that fix nitrogen.
Radishes do not have nodules; they are root vegetables that primarily store nutrients in their fleshy roots. In contrast, beans, which are legumes, do form nodules on their roots. These nodules are home to nitrogen-fixing bacteria, which help the plants convert atmospheric nitrogen into a form they can use for growth. Hence, only beans have nodules, while radishes do not.
