What is the function of bacteria that live on the roots of bean plants?

Question

Piper Anderson · Accepted Answer

The bacteria that live on the roots of bean plants convert nitrogen in atmosphere into amino acids which are utilized for the synthesis of proteins and other nitrogenous compounds.

Biological nitrogen fixation is the process by which bacteria that reside on the roots of bean plants transform atmospheric molecular nitrogen into nitrites and nitrates, which are then transformed into amino acids. These bacteria are helpful to bean plants, and in exchange, the plants receive nutrition from the roots. Because the bacteria and the plant benefit from each other, these bacteria are called symbiotic nitrogen fixing bacteria. These bacteria grow inside the plant's roots and produce nodules, which are called nodulated roots and are present in all leguminous plants, such as peas, beans, gram, and so on.

undefined The function of bacteria that live on the roots of bean plants is to form nodules and engage in a symbiotic relationship with the plant. These bacteria, typically rhizobia, fix atmospheric nitrogen into a form that the plant can utilize for its growth and development. This process is beneficial for both the bacteria and the plant, as the plant receives essential nitrogen while the bacteria receive carbohydrates from the plant.
