Apoptosis is the process of controlled cell death. The cell undergoing apoptosis uses it own energy to efficiently dispose of cellular material with minimal damage to surrounding tissue.
All cells can undergo apoptosis if they reach a stage whereby they recognise (through complex cellular feedback mechanisms) that they are unable to continue operating efficiently.
This is not to be confused with Necrosis, which is an uncontrolled 'catastrophic' cell death pathway. Necrosis is usually a result of serious tissue damage and results in the death of multiple cells in an uncontrolled manner, leaving cellular debree throughout the tissue. This results in inflamation and further damage to the tissue.

What else can I help you with?
What type of cells do not undergo mitosis?
The type of cells that do not undergo mitosis are mature nerve cells and muscle cells.
What might happen if apoptosis did not occur in cells that have significant DNA damage?
If apoptosis did not occur in cells with significant DNA damage, these cells could potentially undergo uncontrolled division and give rise to cancerous tumors. Apoptosis is a natural process that helps prevent the proliferation of damaged cells, so its absence could lead to the survival of mutated cells that may pose a threat to the organism's health.
Cells self destruct through a process called?
apoptosis. During apoptosis, cells undergo a controlled sequence of events leading to their self destruction. This process plays a crucial role in maintaining tissue homeostasis and eliminating damaged or unwanted cells from the body.
Which type of cells do not undergo mitosis?
The type of cells that do not undergo mitosis are the cells in the human body that are considered to be terminally differentiated, such as nerve cells and muscle cells. These cells have exited the cell cycle and do not divide further.
Which cells do not undergo mitosis?
The cells that do not undergo mitosis are sex cells, also known as gametes, such as sperm and egg cells. These cells undergo a different type of cell division called meiosis to produce reproductive cells.
Is apoptosis a feature of malignant cells?
No, that's the opposite, most malignant cells have lost their ability to undergo apoptosis.
What type of cells do not undergo mitosis?
The type of cells that do not undergo mitosis are mature nerve cells and muscle cells.
Why dont cancer cells undergo apoptosis?
In cancerous cells, the normal programming to undergo apoptosis may not be activated due to the nonreception of proapoptotic signals, the decrease or lack of synthesis of proapoptotic signals, the increase in the synthesis of antiapoptotic signals, or a combination of all of these.

What type of cells undergo meiosis?
Cells which produce gametes (sex cells) undergo meiosis.
A class of lipids used to signal cells to undergo changes is called?
The class of lipids used to signal cells to undergo changes is called phospholipids. These molecules play a key role in cell signaling, as they can affect cellular processes such as growth, differentiation, and apoptosis.
Which cells do not undergo mitosis?
The cells that do not undergo mitosis are sex cells, also known as gametes, such as sperm and egg cells. These cells undergo a different type of cell division called meiosis to produce reproductive cells.
Which type of cells, nerve cells or follicle cells, undergo mitosis more frequently?
Follicle cells undergo mitosis more frequently than nerve cells.
How are body cells excreted?
Body cells are not excreted like waste products. Instead, cells undergo programmed cell death (apoptosis) when they age or become damaged. The body then breaks down and recycles these cells through processes like phagocytosis or autophagy.
Contrast apoptosis and cancer?
Apoptosis is a programmed cell death process that occurs in healthy cells to maintain tissue homeostasis, while cancer is the uncontrolled proliferation of cells due to genetic mutations. Apoptosis can help eliminate damaged or unwanted cells, while cancer cells evade apoptosis, leading to tumor development. Understanding the balance between apoptosis and cell proliferation is essential in cancer research and therapy.
