Detailed explanation-1: -When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.
Detailed explanation-2: -Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell.
Detailed explanation-3: -Cells age mostly because they lose a bit of their DNA each time they divide. After around 40 or 50 divisions, they lose too much DNA to keep dividing. They’ve now entered old age. These cells can then continue on doing their jobs or they can die by suicide.
Detailed explanation-4: -Stages of the cell cycle To divide, a cell must complete several important tasks: it must grow, copy its genetic material (DNA), and physically split into two daughter cells.
