Definition
Cell death is a process where a cell ceases to function and ultimately dies. This can occur naturally as part of an organism's growth or development, or it can be triggered by disease or injury.
This is a form of programmed cell death that occurs in multicellular organisms. It's like the planned retirement for a worker who has reached the end of their career.
Necrosis: This is uncontrolled cell death caused by factors outside the cell, such as infection or injury. It's like an unexpected layoff due to external circumstances.
Autophagy: This is a process where the cell recycles its own components to provide necessary building blocks for maintaining cellular functions or adapting to starvation. It’s like repurposing parts from your old car before sending it off to retirement.
