Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R) Assertion (A): The growth of the multicellular organism is due to mitosis Reason (R): Mitosis is also called as equational division and it offers genetic stability
(A) is True but (R) is False.
(A) is False but (R) is True.
Both (A) and (R) are True and (R) is the correct explanation of (A).
Both (A) and (R) are True but (R) is not the correct explanation of (A).
'The growth of multicellular organisms is due to mitosis', making the Assertion true. Additionally, 'Since the number of chromosomes in the parent and progeny cells is the same, it is also called as equational division', and it results in 'production of diploid daughter cells with identical genetic complement', making the Reason true. However, the Reason describes the nature of the division (maintenance of ploidy/stability), which does not directly explain the phenomenon of growth (increase in cell mass/number) itself.
