Sumario:Plant leaves are out of equilibrium active solid sheets that grow in a decentralized fashion by deforming its unit cells while maintaining a typical shape. Here, the authors measure the surface growth of Tobacco leaves at high spatial and temporal resolution, and find that growth dynamics is dominated by sharp fluctuations at the cellular scale, suggesting that it is regulated and correlated in space and time.
