Q. Why the plants do not take nitrogen directly and want to perform nitrogen fixation?
Q. Why the plants do not take nitrogen directly and want to perform nitrogen fixation?
Nitrogen is the most essential element for living organisms. Nitrogen is present in the form of proteins, vitamins, cytochromes, nucleic acid and hormones. Hence, nitrogen is the fundamental constituent of nucleic acid which play vital role in regulating metabolism, growth reproduction and heredity.
therefore plants require nitrogen in larger amount and acts as principal macronutrients. Majority of plants can not utilize nitrogen in elemental form (N2) even though it constituent 78% of earth atmosphere.thus plants unable to uptake atmospheric nitrogen (N2) as such.
There are different source of nitrogen from which plant can directly or indirectly assimilate nitrogen.
Atmospheric gases contain nitrogen in form of nitrogen gas and oxide of nitrogen majority of plants can not assimilate it directly. But some bacteria, blue green algae and leguminous plants can fix the atmospheric nitrogen into available form and assimilate
soil nitrogen present in from of ammonium salts. Well nitrates, nitrires and etc as inorganic nitrogen. Out of these nitrate form can be easily assimilated by higher plants.
Soil nitrogen present in from of ammonium salts. Well nitrates, nitrires and etc as inorganic nitrogen. Out of these nitrate form can be easily assimilated by higher plants
Many soil micro organisms utilize nitrogen in amino acid form which available in soil by decomposition of dead bodies.
Insectivorous plants fulfill their nitrogen requirement by trapping and digesting insects. These plants includes Picher plants, (nepenthes), sundew plant (drosera), Bladderwort (Utricularia), Venus fly trap (Diones) etc. Amino acids in soil (organic from)
