describe necrosis and apoptosis
Answers
Explanation:
Necrosis is a form of cell injury which results in the premature death of cells in living tissue by autolysis.Necrosis is caused by factors external to the cell or tissue, such as infection, or trauma which result in the unregulated digestion of cell components.

Apoptosis
Necrosis
1. Apoptosis
Apoptosis is a regular process of death of the cell that occurs in the body where cell itself takes part in the death
Necrosis
Necrosis is a cellular process of death occurring when the cells are highly exposed to extreme external conditions
2.
It is a natural process and not caused by external factors
It is caused by external agents such as infection, trauma, toxins.
3.
The organelles are still functional even after the death of the cell
The organelles are not functional after the death of cell
4.
The cell membrane breaks into several apoptotic bodies
The cell membrane breaks and releases the cell contents
5.
This process is said to be a bit beneficial. But, is known to be abnormal if in case the cellular processes that keep the body balanced cause many cell deaths or even too few.
It is always damaging or harmful
6.
No symptoms are observed during the process of apoptosis
The symptoms like Inflammation, tissue death and decreased blood flow at the infected site are observed during the process
7.
It is caused due to the self-generated signals within a cell.
It is caused by Bacterial and fungal infections, mycobacterial infections, denatured proteins, pancreatitis, or by the deposits of antibodies and antigens
8.
Not much treatment is required in case of apoptosis
Necrosis, when untreated is said to be very dangerous and can prove to be fatal. Hence, medical treatment is very much necessary in case of necrosis.
9.
This process does not require energy since the enzymes carry out the process.
This process requires energy to carry out the process
