Figure 2. Transformation from cruciform, triradiate and fusiform to oval morphotype.

Figure 2

This transformation involves four stages. In stage 1, the three morphotypes show the characteristics of a thin form indicating that the content of intracellular substances is poor. In stage2, the cells are plump indication many intracellular substances. In stage 3, the overall outline of the cells begins to change. In stage 4, the arms of the three morphotypes gradually disappear and the oval form is observed. Scale bars = 10 μm.
