Vedclass · Answer

(C) Calcium $(Ca^{2+})$ is an essential mineral nutrient for plants. Let's analyze the statements:$(i)$ Calcium is required during the formation of the mitotic spindle,which is correct.$(ii)$ Calcium is not essential for auxin synthesis; Zinc is required for auxin synthesis. Thus,this statement is incorrect.$(iii)$ Calcium is a structural component of the cell wall (calcium pectate) and is relatively immobile in plants. Therefore,it does not accumulate in older leaves; rather,it is found in younger tissues. This statement is incorrect.$(iv)$ It is required by differentiating tissues,which is correct.$(v)$ Calcium is not directly involved in the synthesis of nucleic acids. This statement is incorrect.Therefore,statements $(ii), (iii),$ and $(v)$ are incorrect. However,based on the provided options,the most appropriate choice identifying the incorrect statements is $(ii)$ and $(v)$.

$(a)$ Iron	$(i)$ Photolysis of water
$(b)$ Zinc	$(ii)$ Pollen germination
$(c)$ Boron	$(iii)$ Required for chlorophyll biosynthesis
$(d)$ Manganese	$(iv)$ $IAA$ biosynthesis

Column-$I$	Column-$II$
$(a)$ Calcium	$(p)$ Ferredoxin
$(b)$ Phosphorous	$(q)$ $N_2$-metabolism
$(c)$ Iron	$(r)$ Meristematic tissue
