· The ratio of the volume of the nucleus upon the volume of the cytoplasm is called as Nucleocytoplasmic ratio. · Nucleocytoplasmic ratio = V N / V Cyto = V N / V CELL – V N · In a cell going to divide, nucleocytoplasmic ratio (karyoplasmic ratio) and surface area per unit volume decrease. · The increase in nucleocytoplasmic ratio indicates the increasing activity of cell division. · Smaller cells are metabolically more active than the larger cell due to the high nucleocytoplasmic ratio. · The cell cycle is defined as the sequence of events in which the cell accumulates a large amount of nutrition and then divides into daughter cells. · The process of forming daughter cells from parent cells is called cell division. · A cell divides to maintain the balance between the bulk of cytoplasm and nucleus. CELL CYCLE · The sequence of events that take place between two cell divisions is called the cell cycle. The cell cycle c...
