Cell division is a necessary process that guides the growth and repair of tissues in the body. Cells need to divide to produce new cells and tissues, as well as to fill in size differences between daughter cells.
A cell's life span depends on how many times it can divide. If a cell doesn't divide, it will die. Every time a cell divides, it makes two copies of itself - an identical copy to continue growing, and a new copy that will eventually die.
The cells in our bodies regularly Division throughout our lives, from the day we are born until the day we die. For example: during early development, when embryo cells begin to differentiate into various types of tissue, during fetal development when baby's organs become functional, and throughout adulthood as cells in our skin renew or rebuild after injury or age. The order of events and their timing depend on the particular tissue being replenished--for example, skin renews faster than Bone marrow.
