NEET BIOLOGY

Detailed explanation-1: -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-2: -Apoptosis describes the orchestrated collapse of a cell characterised by membrane blebbing, cell shrinkage, condensation of chromatin, and fragmentation of DNA followed by rapid engulfment of the corpse by neighbouring cells.

Detailed explanation-3: -Apoptosis: is a form of cell death that prevents immune activation. Apoptotic cells have a particular microscopic appearance. The cell activates proteins called caspases that are normally dormant. These caspases dismantle the cell from within.

Detailed explanation-4: -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-5: -What is the definition of apoptosis? Apoptosis is programmed (genetically regulated) cell death. It eliminated cells that are no longer needed or dangerous cells.
