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.
