OBSERVATIONS of natural phenomena such as adventive embryony and production of plantlets from the leaf margins of Bryophyllum support the view that although cells may differentiate and appear to behave differently, their genetic potentialities remain the same. As a corollary to this view, differentiation operates not through a segregation mechanism but due to selective and programmed suppression or stimulation of genie activity.
