nitrogen fixing roots

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 fix..

>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 plant proteins. A..

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 crop..

: 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 fixation When ni..

We can think of a single fixed pulley as a lever of class I where the fulcrum is at the centre and the load and effort arm have the same length. (shown in the figure below) Fixed Pulleys If you pass a string over the pulley with one end carrying a weight and the other end attach..

In dicots the radicle elongates into the primary root which grows downwards into the soil and bears smaller roots as its branches. The primary root grows and becomes the main root or the tap root. The tap root, along with its branches, con..

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 environment as ammonia (ammonifica..

This denotes the number of carbon atoms present in a given molecule. For e.g., C 1 -Meth, C 2 - Eth, C 3 - Prop, C 4 - Bu..

Atmospheric nitrogen can be fixed into usable form by natural processes. Two ways of natural fixation of free nitrogen ar..

Conversion of nitrogen into compounds is essential by combining with carbon, hydrogen and oxygen before it can be absorbed by the plants. This is known as nitrogen fixation. The micro-organisms which can fix atmospheric nitrogen can be classified into two mai..
