Detailed explanation-1: -Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand. In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair. Apoptosis also plays a role in preventing cancer.

Detailed explanation-2: -If cells are no longer needed, they commit suicide by activating an intracellular death program. This process is therefore called programmed cell death, although it is more commonly called apoptosis (from a Greek word meaning “falling off, ” as leaves from a tree).

Detailed explanation-3: -Apoptosis is a form of programmed cell death, or “cellular suicide.” It is different from necrosis, in which cells die due to injury. Apoptosis is not the only form of programmed cell death, but it is the form we understand best.

Detailed explanation-4: -In general, there are three types of cell death, defined in large part by the appearance of the dying cell: apoptosis (also known as type I cell death), autophagic cell death (type II), and necrosis (type III) (Galluzzi et al.

Detailed explanation-5: -Also called programmed cell death.
