#structural growth
- Adnation — A biological or structural phenomenon consisting of the congenital union, fusion, or concrescence of organs or floral parts belonging to different whorls (for instance, the fusion of stamens with the petals of the corolla). This process is essential in plant taxonomy, determining major evolutionary modifications in plant morphology and optimizing pollination mechanisms.
- Auxomery — A structural type or rare biological variation characterized by the unequal division or multiplication of chromosomal segments or metameric structures, leading to a macroscopic differentiation in the growth rate and enlargement of homologous organs of the same plant or living organism.
