Vedclass · Answer

(B) Growth is defined as an irreversible increase in the size or mass of an organism,which is often accompanied by cell division (increase in cell number). During the development of an organism,growth is not just an increase in size; it involves complex processes such as morphogenesis (the development of body shape) and differentiation (cells becoming specialized for specific functions). Both statements are scientifically correct. However,the reason $(R)$ explains the mechanism of growth (cell division),while the assertion $(A)$ describes the developmental outcomes (morphogenesis and differentiation) that accompany growth. Therefore,$R$ is not the direct cause or explanation for why morphogenesis and differentiation occur; they are parallel processes in development. Thus,both are true but $R$ is not the correct explanation of $A$.

Assertion $(A)$: Morphogenesis and differentiation occur during the process of growth.
Reason $(R)$: The number of cells increases during growth.
