Programmed cell death

Programmed cell death (PCD) is the deliberate suicide of an unwanted cell in a multicellular organism.

In contrast to necrosis, which is a form of cell death that results from acute tissue injury and provokes an inflammatory response, PCD is carried out in a regulated process that generally confers advantages during an organism's life cycle.
