Root nodules are special structures that contain nitrogenous bacterias , those stores atmospheric nitrogen to soil.
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.
In nodules on the roots.
they are found growing the roots of plants e.g. cress
These bumps are called nodules
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.
Meat does not have roots. Plants have roots. I think you copied your homework question incorrectly.
They are plants that live with symbiotic bacteria in their roots which form nodules that fix nitrogen.
nodules
Nitrogen-fixing bacteria in nodules on plant roots (legume plants; beans, peas, alfalfa) convert nitrogen in the air (ammonia) to nitrites then nitrates which is then absorbed by plants through their roots.
