Morphogenesis (from the Greek morphê shape and genesis creation, literally "the generation of form") is the biological process that causes a cell, tissue, or organism to develop its shape. It is one of three fundamental aspects of developmental biology, along with the control of tissue growth and the patterning of cellular differentiation.
