Programmed Cell Death

Programmed cell death, also known as apoptosis, is a natural process by which cells systematically shut themselves down when they are no longer needed or are damaged. This mechanism is vital for maintaining the health of an organism, as it helps remove cells that could lead to issues like cancer or other diseases. During apoptosis, a cell undergoes a series of controlled changes, ultimately leading to its self-destruction without causing harm to surrounding cells. This process is essential for growth, development, and the proper functioning of tissues in organisms, ensuring balance and longevity.
