Webfeature distinguishing plants from animals is that the death of a cell and an organ is uncoupled from the death of the whole organism. In this sense, senescence in plants means a genetically well-programmed process that leads to the death of the tissue and organ, rather than just a “wear and tear” of aging. Webcell numbers and cellular positioning within tissues comprised of different cell compart-ments. Programmed cell death (apoptosis) was first described in 1972 by Currie and colleagues.1 It is a common type of cell death associated morphological features that had been repeatedly observed in various tissues and cell types.
