The flagellar photoresponse in Volvox species (Volvocaceae, Chlorophyceae)

Steering their swimming direction toward the light is crucial for the viability of Volvox colonies, the larger members of the volvocine algae. While it is known that this phototactic steering is achieved by a difference in behavior of the flagella on the illuminated and shaded sides, conflicting rep...
