∙ 9y ago
Senescence refers to the process of aging or growing old in living organisms, including plants and animals. It involves a gradual decline in physical and mental capabilities, ultimately leading to deterioration and death. In Biology, senescence is a natural and inevitable part of the life cycle.

Senescence
What is the programmed senescence theory of aging?
The programmed senescence theory suggests that aging is a genetically regulated process designed to limit the lifespan of an organism. It proposes that aging is a result of the activation of specific genes that control the aging process and ultimately lead to the deterioration of cells and tissues over time. This theory contrasts with the idea that aging is simply a result of accumulated damage and wear and tear on the body.
How may the degradation of telomeres result in cellular aging?
The degradation of telomeres, which are the protective caps at the ends of chromosomes, results in cellular aging because each time a cell divides, a small portion of the telomere is lost. As telomeres shorten, it eventually reaches a critical length that triggers cell senescence or programmed cell death. This leads to a reduction in the cell's ability to divide and function properly, contributing to the overall aging of tissues and organs.
Underlying cause of the cellular effects of aging?
The underlying cause of cellular effects of aging is believed to be multifactorial, involving a combination of genetic, environmental, and lifestyle factors. Key factors include DNA damage, telomere shortening, mitochondrial dysfunction, cellular senescence, and inflammation. These processes contribute to cellular and tissue dysfunction over time, leading to the overall aging of the organism.
What comes after middle age for humans?
After middle age, humans enter into the stage of older adulthood or senescence. This stage typically begins around the age of 65 and continues until the end of life. It is characterized by physical, cognitive, and social changes associated with aging, including a gradual decline in various physical abilities and increased risk for age-related diseases.

Define cell senescence in tissue culture?
Senescence is the period between maturity and death; as it relates to tissue culture this is the phase when confluence has been reached (assuming anchorage-dependant cells) and when the media contents contain waste and/or factors to an extent which causes the cells to begin to die-off en masse. The point of tissue culture, typically, is to avoid the senescence phase by regularly changing the media (to dispose of waste products which have toxicity effects), and by subculturing while in log-phase (before the chemical signalling that can cause senescence begins).
What is scientific name for process of leaves changing color?
The scientific name for the process of leaves changing color is "chlorophyll degradation." This natural process occurs in response to factors such as decreasing daylight and temperatures, leading to the breakdown of chlorophyll pigments in leaves and the unveiling of other pigments responsible for the vibrant autumn colors.
