Figure 5.

Response to a changing chemotactic signal. Initially, there is no signal with arrows indicating the time at which a signal is introduced and the signal direction. Note the two figures are not on the same scale and the cells have the same enclosed volume. (a) Chemotactic motion of a cell under conserved surface tension evolution, for parameter values, see table 1 and text. Cell outlines shown every 0.1 units of computational time over the interval [0, 1.8]. (b) Chemotactic motion of a cell under a combination of surface tension and elastic evolution with volume conservation, for parameter values, see table 1 and text. Cell outlines shown every 0.075 units of computational time over the interval [0, 1.725]. (Online version in colour.)
