How does a cell die?

Answer 1

Classically, there are two broad forms of cellular death (though specifically many more subforms).

Those two are apoptosis and necrosis.

Apoptosis is also known as programmed cell death and can be the result of irreparable DNA damage, presence of outside death signals (such as Fas ligand), detachment from the basement membrane (subclassified as anoikis).

Necrosis on the other hand typically is "accidental". Bacterial infection, viral infection, wound damage, burns- by and large, most necrotic events are things that physically disrupt the cell membrane. However, this can also include things like osmolytic lysis or exposure to free radicals (e.g. reactive oxygen species)

Answer 2

This is a broad question. It can either go through apoptosis (programmed cellular death) or necrosis, due to lack of nutrients. There are many ways to kill a cell though...

Answer 3

By apoptosis or necrosis
