Vedclass · Answer

(A) Plants require nitrogen for the synthesis of proteins and other compounds. Although nitrogen is abundant in the atmosphere,plants cannot absorb it directly in its gaseous form $(N_2)$. Most plants absorb nitrogen from the soil primarily in the form of nitrates $(NO_3^-)$ and nitrites $(NO_2^-)$. Some plants can also absorb nitrogen in the form of urea or ammonium compounds,which are converted into nitrates by soil bacteria. Therefore,the forms in which most plants absorb nitrogen are nitrates and nitrites,and sometimes urea.

Choose the forms in which most plants absorb nitrogen:
$(i)$ Proteins
$(ii)$ Nitrates and Nitrites
$(iii)$ Urea
$(iv)$ Atmospheric nitrogen
