What is the biological term for cell death?

What is the biological term for cell death?

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).

What determines the death of a cell?

Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, or may result from such factors as disease, localized injury, or the death of the organism of which the cells are part.

What are the two types of cell death?

Two main types of cell death have been identified: apoptosis and necrosis. Necrosis occurs when cells are irreversibly damaged by an external trauma. In contrast, apoptosis is thought to be a physiological form of cell death whereby a cell provokes its own demise in response to a stimulus.

What is motility in cells?

Definition. Cellular motility is the spontaneous movement of a cell from one location to another by consumption of energy. The term encompasses several types of motion, including swimming, crawling, gliding and swarming.

What is autophagy cell death?

Also known as type 2 cell death, autophagic cell death (ACD) is morphologically defined (especially by transmission electron microscopy) as a type of cell death that occurs in the absence of chromatin condensation but is accompanied by large-scale autophagic vacuolization of the cytoplasm (see figure, part b).

What is cell autophagy?

Autophagy is the body’s way of cleaning out damaged cells, in order to regenerate newer, healthier cells, according to Priya Khorana, PhD, in nutrition education from Columbia University. “Auto” means self and “phagy” means eat. So the literal meaning of autophagy is “self-eating.”

What does motility mean in biology?

adjective. Biology. moving or capable of moving spontaneously: motile cells; motile spores.

How do you describe motility?

Motility is the ability of a cell or organism to move of its own accord by expending energy. Most animals are motile, using means such as walking, slithering, swimming, and flying to propel themselves through the world.

What is autophagy?

So the literal meaning of autophagy is “self-eating.”

How is autophagy induced?

In order to work efficiently and survive, cells have to continuously detect and adapt to their environment. Autophagy is induced under a number of stresses, including starvation, organelle/DNA damage, hypoxia, ER stress, and pathogen infection.

What is called motile?

Motile organisms can move. Some doctors are concerned with how motile a person’s digestive system is, or how efficiently food is moving through it. The movement itself is called motility, and both words come from the French motilité, from the Latin motus, or “motion,” with motile copying the form of mobile.

What are the types of motility?

Types of Motility

• Muscles. Most animals move by making use of muscles.
• Hydraulic Movement. Some arthropods, such as spiders, actually use hydraulic movement.
• Flagellar Motility.
• Amoeboid Movement.
• Swarm Motility.
• Gliding Motility.
• Sperm.
• Humans.
