Immunofluorescence images reveal that there is a connection between the eyespot and the close by cilium of Chlamydomonas reinhardtii. Cilia and cytoskeleton parts are labeled green and reach the channelrhodopsin receptors in the eyespot area, labeled magenta. The antibody against channelrhodopsin was kindly provided by Peter Hegemann. Photo: © Thomas Nolte and Maria Mittag, University Jena
The video shows the helical movements of Chlamydomonas reinhardtii in the light microscope. Related to its body index C. reinhardtii swims approx. 12 times faster than the world record holder in 50-m breast-stroke swimming. Video: © Thomas Nolte and Maria Mittag, University Jena
A liquid stream pushes three Chlamydomonas reinhardtii cells into pockets. The 4 x faster video shows the movement of the cilia and the pumping of the contractile vacuoles situated close to the cilia to remove excess water. © Karin Komsic-Buchmann und Burkhard Becker, University Cologne.
