Article Description

Cryptomonads are unicellular algae with a unique photosynthetic apparatus, both in structure and pigment composition. A cryptomonad, Rhodomonas lens (R. lens), was studied by conventional electron microscopy, freeze-fracture, and freeze-etch in order to determine whether the thylakoids of this alga are everted with respect to those of other plants, as has been postulated (Ganttet al. 1971, Gantt 1979, 1980) as a means to compensate for the location of the cryptomonad light-harvesting apparatus on the opposite side of the thylakoid membrane from that of related algae. We have characterized the thylakoids of this alga and conclude that they are not everted, but are oriented in the same manner as those of other algae and green plants. Implications for energy transfer are discussed. © 1985 Springer-Verlag.
