What is dedifferentiation?
Dedifferentiation is the process by which the differentiated cells regain their capacity to divide, e.g. interfascicular cambium and cork cambium formed by fully differentiated parenchyma cells.
Biological Nitrogen Fixation is done by some specific prokaryotes. They use nitrogenase enzymes for catalyzing the conversion of nitrogen in the air to ammonia. In this process, atmospheric nitrogen is incorporated into the tissues of some plants. Only some groups of plants have the capability to acquire such nitrogen with the aid of microbes present in the soil. Legumes amongst the forage plants can obtain nitrogen from the atmosphere.
