$S$ and $R$ are both true, but $R$ is not the correct explanation of $S$.

Vedclass · Answer

(B) The $Assertion (S)$ is true because the cell cycle is a fundamental process in all living organisms, ensuring that every newly formed cell undergoes growth and division to maintain the continuity of life.The $Reason (R)$ is also true because plant cells do not possess centrioles, which are typically found in animal cells and are involved in spindle fiber formation.However, the absence of centrioles in plant cells is not the reason why cells follow the cell cycle. The cell cycle is a universal biological process regulated by cyclins and cyclin-dependent kinases $(CDKs)$, independent of the presence or absence of centrioles. Therefore, $R$ is not the correct explanation for $S$.

Option	Figure $A$	Figure $B$
$(a)$	Metaphase	Telophase
$(b)$	Telophase	Metaphase
$(c)$	Late anaphase	Prophase
$(d)$	Prophase	Anaphase

$Assertion (S)$: Every newly formed cell follows the cell cycle.
$Reason (R)$: Plant cells lack centrioles.
