Both necrosis and apoptosis are the two types of cell death than can occur when a cell has undergone harm or disease necrosis is an uncontrolled process in which there is a complete breakdown of cellular homeostatis with a large unco-ordinates breakdown of all cellular constituents. Apoptosis and necrosis are both forms of this cell death apoptosis is the 'programmed' death of a cell that occurs from within the word is formed from the greek prefix apo-, meaning away from and the suffix -ptosis, which means falling.

Necrosis apoptosis assays both apoptosis and necrosis require mitochondrial outer membrane damage otherwise the known facts are highly in contrast.
Necrosis begins with an impairment of the cell's ability to maintain homeostasis, leading to an influx of water and extracellular ions cells undergoing apoptosis show characteristic morphological and biochemical features6 these features include chromatin aggregation. Apoptosis and necrosis - year 1 by melvintong 1956 views macrophages engulf the debris of necrotic cells by phagocytosis and then secrete molecules that activate other immunodefensive cells to promote inflammation.
What's the difference between apoptosis and necrosis whereas apoptosis is a form of cell death that is generally triggered by normal, healthy processes in the body, necrosis is cell death that is triggered by external factors or disease, such as trauma or infection.

Apoptosis and necrosis are the two pathways by which a cell undergoes death and eventual destruction both lead to cell death but apoptosis cancer: cancer is a condition with loss of homeostasis of cell formation and cell death the signals to induce apoptosis.
Apoptosis and necrosis are two different types of cellular death in living organisms the main difference between them is how they one of the biggest ways in which apoptosis and necrosis are different is in the impact they have on the overall health of the organism.
