Cell Cycle

Cell Cycle. **The cell cycle or the cell division cycle is a series of events that take place when a cell is going to divide and reproduce a new cell. This process must take place when: A fertilized egg develops into a multicellular organism An organism must replace cells that have

Why Cells divide?

Why Cells divide?. In unicellular organisms , division of one cell reproduces the entire organism Multicellular organisms depend on cell division for: Development from a fertilized cell Growth Repair of injured tissues. DNA is the genetic material of the cell.
