Figure 6. Directional displacement.

Pseudopod formation and trajectories were recorded for 5h starved Dictyostelium cells; 8 cells were followed during 15 min. The directional displacement is the distance moved after n pseudopodia in the direction of the first pseudopod. Data points are the means of ∼120 measurements, the line is the outcome of Eq. 11 with pseudopod parameters as indicated in Table 1.
