Simulation of growth with uniform turgor pressure—all cell walls remain straight. (A) Normal growth of a 2D cellular structure giving the initial state at t = 0 when cell divisions become inhibited (dimensions of simulation box ≈4.2 × 3.7). (B) The 2D cellular structure resulting from the same simulation at time t = 1 after the inhibition of cell divisions (dimensions ≈86 × 75); cells with <6 sides tend to vanish relatively. (C) Cell area versus time; dotted lines correspond to individual cells having different numbers of sides, the solid line to an average over all cells.
