The two flagella of Chlamydomonas are known to beat synchronously: During breaststroke beating they are generally coordinated in a bilateral way while in shock responses during undulatory beating coordination is mostly parallel [Ruffer and Nultsch, 1

Phototaxis in wild-type Chlamydomonas cells is probably the result of four single photoresponses in the flagella, inverse in the cis (near the eyespot) and in the trans flagellum and also inverse by step-up (increase of) and step-down (decrease of) l

Photoinhibition of photosynthesis of the brown alga Dictyota dichotoma was studied by measuring changes of photosystem II fluorescence, oxygen production and xanthophyll pool (zeaxanthin, antheraxanthin and violaxanthin). The experiments were carried

Using high-speed microcinematography flagellar shock responses of a great number of Chlamydomonas cells, free-swimming as well as immobilized on micropipettes, were investigated in this study. Responses were elicited by flashes, by blue, red or white
