DESCRIPTION:Shape in an organism is often thought to be closely related to
  its function. The puzzle-shaped epidermal cells that appear in the epider
 mis of many plants are a striking example of a complex cell shape\, howeve
 r their functional benefit to the plant has remained elusive. We propose t
 hat the creation of these complex shapes is an effective strategy to reduc
 e mechanical stress in the cell wall. Although the formation of these shap
 es requires highly anisotropic and non-uniform growth at the sub-cellular 
 level\, it appears to be triggered by isotropic growth at the organ level.
  A re-analysis of recently published data suggests that this constraint is
  conserved among the land plants.
