Scanning Electron Micrographs of Mating Chlamydomonas
Mating begins when walled gametes are mixed
Flagellar signaling leads to cAMP production, flagellar tipping and release of the enzyme autolysin, that digests the cell walls.
The mating structure of the plus cell contacts the mating structure of the minus cell leading to adhesion.
The cells then fuse at the point of contact of the two mating structures.
