Mechanical Self-Assembly vs. Morphogenesis

Morphogenesis, as one of the three fundamental aspects of developmental biology, refers to the biological processes of developing certain shapes, which takes place across many length scales, including the morphologies of a cell, a tissue, an organ, and a system. From the intrinsic yet complicated biological and biochemical perspectives, several mechanisms for plant pattern formation have been suggested, such as positional information theory [1] and reaction–diffusion theory [2]. However, the active role of mechanical forces should not be underemphasized.
