what is nitrogen fixing bacteria live in these structures found in the roots of legumes
Rhizopus bacteria is found in the roots of legumes
In root nodules of lupins and other legumes.
In soil. Especially around certain plants (legumes).
Legumes have nirtifying bacteria in their roots, but mostly they are found in the soil.
The five major structures found in bacteria are capsule,ribosome,nucloid,flagella pilli,cytoplasm and pilus also
Legume plants are notable for their ability to fix atmospheric nitrogen, thanks to a symbiotic relationship with certain bacteria known as rhizobia found in root nodules of these plants. The ability to form this symbiosis reduces fertilizer costs for farmers and gardeners who grow legumes, and allows legumes to be used in a crop rotation to replenish soil that has been depleted of nitrogen. The nitrogen fixation ability of legumes is enhanced by the availability of calcium in the soil and reduced by the presence of ample nitrogen. Root nodules. via Wikipedia
Legumes have nitrogen-fixing bacteria found in nodules on their roots. Thus, they add nitrogen fertilizer to the soil.
chromatin, ribosomes, chloroplast
The two main groups of bacteria responsible for nitrogen fixation are Rhizobium found in legume root nodules, and Azotobacter found in the rhizosphere of various plants. Rhizobium forms a mutualistic relationship with legumes, providing fixed nitrogen in exchange for sugars, while Azotobacter functions as a free-living nitrogen fixer in the soil.
Cell Walls
There are not 6 but 5 main structures found in bacterial cells. They are DNA, cell membrane, ribosomes, surface layer and the cell wall.
Ribosomes are not bacteria. They are microscopic structures containing proteins and strands of RNA. They are located within the cytoplasm of plant and animal cells.
