Figure 1: Chlamydomonas reinhardtii alga modeled as three spheres (blue), where the central one is the body and the outer two are the flagella. The triangle connects the body and the centers of motion of the flagella, which move in the direction of the arrows in synchronized beating. Superimposed on the spheres is a sketch of the actual alga (green).
