Description: Transmission electron microscope image, showing an example of green algae (Chlorophyta). Chlamydomanas reinhardtii is a unicellular flagellate used as a model system in molecular genetics work and flagellar motility studies. This image is a longitudinal section through a portion of the flagellar apparatus. In the cell apex are the basal body regions that are the anchoring sites for the flagella. This image shows that the two flagella form a V and they are connected at their bases by a transversely striated fibre. This connection is thought to play a part in the coordination of flagellar movement. Also visible is the transition region, with its fibers of the stellate structure. JEOL 100CX TEM.
