Senescence
noun
The condition or process of becoming old.
The plant is at the stage of senescence, which is why it is showing signs of decay.

Often appears as...
- cellular senescence
- plant senescence
Usage tips
Technical, General
noun
The natural period in the life of an organism in which it ceases to be physically capable of reproduction and growth, eventually leading to decay and death.
The onset of senescence in varied organisms seems to be associated with specific genetic factors.

Nature's Cycle
Senescence implies the natural aging process in all living beings, not just humans.

Even stars undergo senescence, gradually losing their shine.
Not Just Age
It involves not only aging but also the decline in function that comes with it.

The senescence of the old tree made it vulnerable to disease.
Technical Term
Often used in scientific or technical contexts, less in everyday language.

Studying senescence can help us understand life cycles better.

S. Jay Olshansky
American Scientist
You can open up a centenarian's brain, and you'll see some areas that look like that of a 50-year-old or of a 110-year-old. You can have variation in the basic process of aging, called senescence, in different parts of the same body.

Quote examples
Aubrey de Grey
English Author
We've spent the last few millennia aware that senescence is horrible but knowing nevertheless that it's inevitable. We've had to find some mechanism to put it out of our minds so we can get on with our miserably short lives.

Quote examples
S. Jay Olshansky
American Scientist
The evolutionary theory of senescence can be stated as follows: while bodies are not designed to fail, neither are they designed for extended operation.

Quote examples
George C. Williams
American Scientist
The general rule is that anything that is passed on in reproduction does not undergo senescence.
