Question

Define senescence in plants.

Answer 1

It is the process of aging in plants in which cells reach permanent growth arrest without the death of cells as the whole cell division process comes to a termination. It is characterized by a gradual functional decline eventuating heterogeneously across organ systems, leading to a progressive deterioration ultimately leading to dysfunctioning of tissue. It can either occur at the cellular level or senescence of the whole organism can take place.
