Final answer:
Cells die through a process called apoptosis, which is programmed cell death. This occurs when cells are damaged, superfluous, or potentially dangerous to an organism. Apoptosis allows cells to die in a controlled manner, preventing the release of potentially damaging molecules.
Step-by-step explanation:
Cells die through a process called apoptosis, which is programmed cell death. This occurs when cells are damaged, superfluous, or potentially dangerous to an organism. Apoptosis allows cells to die in a controlled manner, preventing the release of potentially damaging molecules. There are internal checkpoints that monitor a cell's health, and if abnormalities are observed, the cell can initiate apoptosis. External signaling can also trigger apoptosis, such as when cells move away from the extracellular matrix, and the signaling ceases.
