Morphogenesis is the generation of ordered form and structure. This process proceeds along with cell diff erentiation. The primary mechanisms of morphogenesis are cell shape change and cell migration. Apoptosis is programmed cell death that is a necessary part of morphogenesis. Cell migration in animals involves alternating changes in adhesion brought about by cadherins and integrins. In plants, which cannot move, cell division and cell expansion are the primary morphogenetic processes.
