What is programmed cell?
A cell dies as a result of internal processes like apoptosis or autophagy, which is referred to as programmed cell death. PCD is a biological process that typically benefits an organism throughout its existence. For instance, in a growing human embryo, cells between the fingers apoptosis, causing the digits to become distinct. During the development of both plant and animal tissue, PCD performs essential roles.
Both apoptosis and autophagy are types of planned cell death. Necrosis, which can take many various forms, is the death of a cell brought on by outside forces such as injury or infection. For a long time, necrosis was believed to be an unphysiological phenomenon.
