The unicellular Chlamydomonas exhibits two flagella whose beating enables it to swim in a breast stroke towards light, a nowadays widely studied behaviour favouring photosynthesis. One also finds Gonium, an algae made of 16 Chlamydomonas-like cells. It is flat and squared, with all flagella on one side of the plate. This simple algae is a key organism to understand the evolution from unicellular to multicellular coherent behaviour. Pour plus d'informations, merci de contacter Truzzolillo D. |
