$A$ and $R$ are both true,but $R$ is not the correct explanation of $A$.

Vedclass · Answer

(B) is true: Plants primarily absorb nitrogen from the soil in the form of nitrates $(NO_3^-)$ or ammonium ions $(NH_4^+)$,which are salts.$R$ is true: Nitrogen is a critical component of amino acids (the building blocks of proteins),nucleic acids ($DNA$ and $RNA$),vitamins,and chlorophyll.Conclusion: While both statements are scientifically correct,the fact that nitrogen is essential for protein synthesis $(R)$ does not explain why plants absorb it as salts from the soil $(A)$. The absorption mechanism is determined by the chemical availability in the soil solution,not by the biological function of nitrogen. Therefore,$R$ is not the correct explanation of $A$.

Column-$I$	Column-$II$
$(A)$ Found in some amino acids	$(1)$ $Mg$
$(B)$ Required for photolysis of water	$(2)$ $I$
$(C)$ Not important for plants	$(3)$ $S$
$(D)$ Structural component of chlorophyll	$(4)$ $Mn$

$A$: Plants absorb nitrogen from the soil in the form of salts.
$R$: Nitrogen is essential for the synthesis of proteins and nucleic acids.
