Figure 1
Schematic representation of the unicellular green algae Chlamydomonas and its eyespot. The cell is ≈10 μm in diameter, the eyespot is 1 μm in diameter, and the flagella are ≈10 μm long. The blow up to the right is a cross section of the eyespot through the various algal membranes. The photoreceptor pigment most likely is localized in the cell's outer, plasma membrane. As the cell swims with its two flagella, it also rotates around the axis along which it is progressing. The dense pigment indicated as a set of colored circles in the eyespot can shield the photoreceptor pigment from light coming from one direction as compared to the other such that the swimming, rotating Chlamydomonas can continuously sample the spatial distribution of light. The figure is courtesy of Ella Imasheva (University of Washington, Seattle).
