Focus on a project

How do colonial micro-algae swim towards light?

F. Moisy

Collaboration: H. de Maleprade and R. Goldstein (DAMTP Cambridge), T. Ishikawa (Tohoku University)

Unicellular flagellate microalgae like Chlamydomonas are able to swim in the direction of light in order to optimize photosynthesis: this is phototaxis . This biased swimming towards light is performed thanks to a differential action of the flagella according to the perceived light incidence. How is this property transmitted to its close relative Gonium , a small colony made of 8 to 16 cells assembled as a plate, capable of swimming along intriguing helical trajectories towards the light? We have developed a hydrodynamic model that relates the individual cell behavior to the apparently coordinated swimming of the colony.
