Pulse plants have nodules to help them convert nitrogen in the atmosphere to ammonia that can be used by the pulse plants to manufacture amino acids, proteins, nucleic acids, and other nitrogen-containing compounds that are necessary for the pulse plants to survive.
The conversion of atmospheric nitrogen into ammonia is called nitrogen fixation. The nitrogen fixation process starts with the formation of nodules.
Rhizobium is a common soil bacterium which invades the roots of the pulse plant and multiplies within the cells of the cortex layer. Within a week after infection small nodules are visible to the naked eye.
The nodules grow and turn pink or reddish in color indicating that the process of nitrogen fixation has started.
The nitrogen goes into the nodules of the plant.
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.
Plants with root nodules are commonly referred to as "leguminous plants" or "legumes." These plants, which belong to the family Fabaceae, form symbiotic relationships with nitrogen-fixing bacteria, allowing them to convert atmospheric nitrogen into a form usable by plants. This adaptation enhances soil fertility and is beneficial in agricultural practices. Examples include beans, lentils, and peas.
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.

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.
