WebOct 12, 2024 · The radius of observed Chlamydomonas cells was calculated and shown in Figure 9a. These results indicate that the fluorescence camera can detect the fluorescence signals generated by Chlamydomonas cells with a DoF of more than 0.8 mm. The large DoF can provide two advantages: (i) higher volumetric throughput since thick fluid … WebThe cells of anterior end possess bigger eye spots than those of posterior end cells. The cells of posterior side become reproductive on maturity. Thus, spherical or round colony of Volvox shows clear polarity. The cells of Volvox colony are Chlamydomonas type. Every cell has its own mucilage sheath (Fig. 1 B).
