Cell Cycle: Introduction
- All cells reproduce by dividing into daughter cells.
- Therefore, cell cycle can be defined as an orderly set of stages that take place when a cell divides and then the daughter cells also divide.
- Hence, the sequence of events by which a cell duplicates its genome, synthesises the other constituents of the cell and eventually divides into two daughter cells is termed cell cycle.
- The cell cycle is divided into the following phases:
(a) Interphase
(b) Division phase
Utility of Cell Division:
- Cell division enables a single cell to eventually produce many cells, allowing an organism to grow and develop.
- Cell division also occurs when a repair is needed and worn-out tissues have to be replaced.
- Cell division results in the formation of gametes that fuse to form the zygote. Hence, the reproduction and restoration of the chromosome number is maintained by the cell division.
- In unicellular organisms, cell division results in the reproduction of the organism.
