A cell divides when its karyocytoplasmic index or karyoplasmic index

Options

  1. ADecreases
  2. BIncreased
  3. CRestored
  4. DRemain same

Correct answer

A. Decreases

Step-by-step solution

Karyoplasmic index is the ratio of the volume of the nucleus to the volume of the cytoplasm. For each cell fixed volume of nucleus can control the fixed volume of cytoplasm, when the volume of the cytoplasm increases more than the volume of the nucleus the karyoplasmic index decreases. Thus the cell starts dividing.
