these bacteria are known as rhizobium. they synthesis the atmospheric nitrogen into nitrates & nitrites soluble in soil
Legumes have nitrifying bacteria in their roots, but mostly it is found in the soil. Although the air is made up of about 78% 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
The nitrogen-fixing bacteria live in the root nodules of legumes.
Leguminous plants, such as legumes (e.g., peas, beans, alfalfa) and clover, have root nodules that contain nitrogen-fixing bacteria (like Rhizobia) that convert atmospheric nitrogen into nitrates through a process called nitrogen fixation. This capability makes them valuable for improving soil fertility and reducing the need for synthetic fertilizers.
Bacteria performs nitrogen fixation, which involves converting the atmospheric nitrogen (N2) into usable organic nitrates (NO3-). Said bacteria are often referred to as nitrogen fixating bacteria. The process is sometimes called nitrification.Scientists have been able to give plants genes from bacteria to help them do a beeter job. This process is called recombinant DNA technology. Nitrogen fixing bacteria are in root nodules on legumes and maybe some other plant groups.Converts nitrogen in the air to nitrates.

what is nitrogen fixing bacteria live in these structures found in the roots of legumes
Nitrogen-fixing bacteria are the organisms that convert atmospheric nitrogen into a form that is usable by plants, which in turn are consumed by humans as food. Legumes such as peas, beans, and clover have a symbiotic relationship with these bacteria, allowing them to convert nitrogen into a usable form for plants.
Nitrogen fixation occurs in1 free living bacteria and archaea e.g. Azotobacter, Klebsiella, Clostridium, and Methanococcus,2 bacteria living in symbiotic association with plants such as legumes e.g. Rhizobium3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.
It is not so much the class of plants that do this directly but rather a class of plants that support nitrogen binding bacteria in their root nodules - these plants are the 'legumes' such as peas, beans and clover.
The bacteria fix nitrogen by converting it to ammonia and nitrates which the plant can absorb and use to build its nitrogen containing molecules such as amino and nucleic acids. In return it offers some of its own sugars to the bacteria to cover their needs. It's a trade off between biologically usable nitrogen and sugar
