Programmed cell death in which the cell responds to certain signals by initiating a normal response that leads to cell death is:
Correct answer: D. Apoptosis
- A. Cell Induction
- B. Necrosis
- C. Inflammation
- D. Apoptosis
- E. Cellular Dysgenesis
Explanation
Apoptosis, often referred to as programmed cell death or cellular suicide, is a highly regulated and essential process in multicellular organisms. It plays a critical role in maintaining tissue homeostasis, development, and eliminating damaged or unwanted cells from the body. Apoptosis is distinct from necrosis, which is uncontrolled cell death due to injury or trauma. The internal programme of events and sequence of morphological changes by which a cell commits suicide is collectively called apoptosis (a Greek word that means dropping off or falling off).

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
