*Firstly, cells does not needed anymore. When a baby is in mother’s womb, his fingers or toes are connected each other by connective tissue. While he is growing up, the connective tissue is disappeared by cell death (apoptosis). If the connective tissue does not killed by apoptosis, the baby’s fingers will attach as a duck’s feet. | *Firstly, cells does not needed anymore.

*Secondly, longer living cell becomes a cancer. When the cells live longer, they have a genetic problem or damage. Finally the damage leads the cells to become the cancer. Without apoptosis, there is possibility that cells become the cancer. | *Secondly, longer living cell becomes a cancer. When the cells live longer, they have a genetic problem or damage.

Even though apoptosis is programmed cell death, it plays an important role in the life of an organism. Apoptosis helps to form the overall body shape and the shape of organs. In the immune system, apoptosis plays an important role that eliminates aggressive immune cells.

Apoptosis plays an important role in immune system. Every person has white blood cells and red blood cells. If a person has more number of white blood cells than number of red blood cells, he will have a caner. If apoptosis plays its own role (programmed cell death), he will not have the cancer (follicular large-cell lymphoma). Unfortunately the white cells do not die, but they keep dividing. By dividing white blood cells, mutation occurs. Finally he dies by over population of white blood cells. | Apoptosis plays an important role in immune system.
