Question

(D) The Assertion is incorrect because the process of nitrification involves the oxidation of ammonia $(NH_3)$ to nitrite $(NO_2^-)$ by $Nitrosomonas$

Vedclass · Accepted Answer

Both Assertion and Reason are incorrect.

Vedclass · Answer

(D) The Assertion is incorrect because the process of nitrification involves the oxidation of ammonia $(NH_3)$ to nitrite $(NO_2^-)$ by $Nitrosomonas$ and $Nitrococcus$,and then nitrite is oxidized to nitrate $(NO_3^-)$ by $Nitrobacter$. The statement in the Assertion reverses the order of products.The Reason is also incorrect because plants primarily absorb nitrogen in the form of nitrate $(NO_3^-)$ or ammonium $(NH_4^+)$ through their roots,not through their leaves. Once absorbed,nitrate is transported to the leaves where it is reduced back to ammonia to be incorporated into amino acids.

Section $A$	Section $B$
$(i)$ Nitrosomonas	$(a)$ Nitrite $\rightarrow$ Nitrate
$(ii)$ Agrobacterium	$(b)$ Nitrogen fixative bacteria
$(iii)$ Rhizobium	$(c)$ $NO_3^- \rightarrow N_2$
$(iv)$ Nitrobacter	$(d)$ Ammonia $\rightarrow$ Nitrite
	$(e)$ Denitrifying bacteria

$A$: Ammonia is oxidized first to nitrite and then to nitrate by the action of $Nitrosomonas$ and $Nitrobacter$ respectively.
$R$: Nitrite thus formed is absorbed by leaves.
