Vedclass · Answer

(A) The $K.I$ (Karyoplasmic Index) is defined as the ratio of the volume of the nucleus $(V_n)$ to the volume of the cytoplasm $(V_c)$,expressed as $K.I = V_n / V_c$.During cell growth,the volume of the cytoplasm increases significantly as the cell synthesizes proteins and organelles,while the volume of the nucleus remains relatively stable.Since the denominator $(V_c)$ increases while the numerator $(V_n)$ remains constant,the overall value of the $K.I$ decreases.When the $K.I$ falls below a critical threshold,it triggers the cell to undergo division to restore the balance between the nucleus and the cytoplasm.
