It is shown here that the unicellular alga Chlamydomonas does indeed use a rhodopsin photoreceptor, and that 11-cis-retinal is the natural chromophore and that the protein environment of this retinal is similar to that found in bovine rhodopin, suggesting homology with the r Rhodopsins of higher organisms.
