Senescence is the process of the aging of cells which eventually leads to cell death. Many people think that if senescence was prevented, people could live much longer, if not forever. There is even an area of science, called gerontology, that studies the aging process in order to prevent age-related diseases and disabilities. | Senescence is the process of the aging of [[cells]] which eventually leads to cell [[death]].

[[Ethylene]] is an important senescence hormone in plants because it stimulates plant growth and speeds up the process of apoptosis. Ethylene also is involved in the abscission of leaves and the fading of flowers. | [[Ethylene]] is an important senescence hormone in plants because it stimulates plant growth and speeds up the process of apoptosis.
