Cellular multiplication occurs through which process?

Match List-$I$ with List-$II$ :

List-$I$ (Phase of cell cycle)	List-$II$ (Activity)
$A$. $G_1$ phase	$I$. Actual cell division occurs
$B$. $S$ phase	$II$. Cell is metabolically active and continuously grows but does not replicate its $DNA$
$C$. $G_2$ phase	$III$. Synthesis of $DNA$ occurs and the amount of $DNA$ per cell doubles
$D$. $M$ phase	$IV$. Proteins are synthesized while cell growth continues

Choose the correct answer from the options given below :

Cell division occurs . . . . . . in plants and . . . . . . in animals.

Which of the following is true for a syncytium?

Analyse the events during every stage of the cell cycle and notice how the following two parameters change:
$(i)$ Number of chromosomes $(N)$ per cell
$(ii)$ Amount of $DNA$ content $(C)$ per cell

Match the following columns correctly:

Column $I$	Column $II$
$(a)$ $G_1$ phase	$(p)$ Synthesis of new $DNA$ occurs
$(b)$ $G_2$ phase	$(q)$ No $DNA$ synthesis occurs
$(c)$ $S$ phase	$(r)$ $DNA$ synthesis stops
$(d)$ Prophase	$(s)$ Formation of mitotic spindle occurs
