Vedclass · Answer

(B) Statement $X$ is true because cell division is the fundamental process that allows organisms to grow,develop,and repair tissues.Statement $Y$ is true because,for a cell to divide,it must first replicate its genetic material ($DNA$ replication) and then ensure that the replicated $DNA$ is equally distributed into the daughter cells ($DNA$ segregation).Since the growth of an organism (Statement $X$) is a direct consequence of the increase in cell number,which is achieved through the processes described in Statement $Y$,Statement $Y$ provides the mechanistic explanation for Statement $X$.

Column-$I$	Column-$II$
$(I)$ $M$ phase	$(i)$ Nucleolus,golgi complex and $\text{ER}$ reform
$(II)$ Telophase	$(ii)$ No replication of $\text{DNA}$
$(III)$ Diakinesis	$(iii)$ Most dramatic period of the cell cycle
$(IV)$ Interkinesis	$(iv)$ Terminalisation of chiasmata

Statement $X$: The process of cell division is essential for the growth of an organism.
Statement $Y$: Replication of $DNA$ and division of $DNA$ are necessary for cell division.
