Conclusion – Senescence
Senescence definition states that it is a biological process that involves cells aging and permanently stopping cell division. It can either occur at the cellular level or senescence of the whole organism can take place. Senescent cells are those cells that have stopped dividing but remain alive and release chemicals that can cause inflammation. Senescence benefits a plant by protecting it from disease, causing only one part of the plant (such as a tree branch) to die so that the rest of the plant can live. It also benefits plants by allowing it to go into a state of dormancy until favorable growing conditions return.
What is Senescence? – Senescent Cells And Senescence In Plants
Senescence is the process by which cells stop dividing and enter a state of permanent growth arrest without undergoing cell death. Senescence cells get old and weaken, causing a decline in tissue function and decay. Senescence in plants is a programmed death of leaves as part of developmental cycles. In animals, senescent cells contribute to aging and age-related diseases.
Senescence can be induced by unrepaired DNA damage or other cellular stresses. It plays a role in normal development, maintains tissue homeostasis, and limits tumor progression. In this article, we will read about what is senescence, its causes, and effects, senescent cells, the different types of senescence in plants, theories of aging, factors affecting senescence, and its importance.
