EXPERIMENT 7 (BNU+UPMC, December 2013, March 2014)
Euglena gracilis: unicellular micro-organism (half plant - half animal)

  • Explanations


    f1 (macroscopic clustering pattern, 3cmx3cm), f2 (far from a clustering area), f3 (near a clustering line)


    f4 (near clustering centers, 6mmx6mm), f5(between slide+cover slip, x90), f6(between slide+cover slip, x225)

  • FILM (10Xd.mov): transition zone between a cluster and the surrounding population
    In this experiment the euglenas were confined in a thin (with a thickness of about 80 micrometers) layer of water surrounded in the x-y plane by a roll of oil and comprised in the z-direction between two thin glass plates. This experiment was performed in the group of Prof. Michel Gho to whom we express our gratitude.
