why are nitrogen fixing bacteria important to plants

>The nitric oxide so formed then reacts with more oxygen to form nitrogen dioxide. Nitrogen dioxide so formed, gets washed down by rain and forms nitrates and nitrites in the soil. Plants absorb these of nitrates and nitrites from the soil and convert them into pl..

Nitrogen Fixing Organisms - Some bacteria are known to fix the atmospheric nitrogen for their own biological activity. This natural phenomena is commercially utilized to increase the nutrient supply to crops. There are two types of nitrogen..

Certain plants such as peas, beans, etc., have some special kind of nitrogen fixing bacteria (symbiotic bacteria) in the nodules of their roots. These bacteria fix free nitrogen of the air as nitrogen compoun..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the envi..

: Rhizobium, a nitrogen fixing bacteria present in the roots of leguminous plants, fixes atmospheric nitrogen to the soil. Azotobacter and Clostridium are other free-living nitrogen fixing bacteria. Physical f..

Nitrogen Metabolism in Plants - Nitrogen is one of the important elements found in living organisms. Supply of nitrogen from the atmosphere is maintained. Nitrogen is an essential constituent of amino acids and hence the proteins cannot be..

Nitrogen is one of the important elements found in living organisms. Supply of nitrogen from the atmosphere is maintained. Nitrogen is an essential constituent of amino acids and hence the proteins cannot be absorbed by the plants directly fro..

>When nitrogen is heated with calcium carbide at 800 o C to 1000 o C, nitrolim an important fertilizer is formed. Nitrogen is used in high temperature thermometers, as a refrigerant and in electric bulbs. Nitrogen cycle charts the circulation of nitrogen..

1) They produce food for all organisms 2) They provide beneficial substances like drugs, tannins, fibres, rubber, vegetable oils, fuel, condiments. 3) Some plants contain alkaloids which check growth of cancer cells. Example: Rosy periwinkle. 4) Plants release O ..
