Definition of geotaxis in English:



  • [mass noun] The motion of a motile organism or cell in response to the force of gravity.

    • ‘They cause a variety of behavioral phenotypes including overall sluggishness and abnormal phototaxis, geotaxis, flight ability, ether recovery, and mating vigor.’
    • ‘It therefore seems that positive phototaxis was stronger than the positive geotaxis as a driving force of cell motility.’
    • ‘Groups of Hies are introduced into the top of the cylinder, where they remain temporarily due to their natural propensity for negative geotaxis.’
    • ‘This suggests that the fusion of response observed in geotaxis and phototaxis also exists in more sophisticated forms of navigation.’
