kinesis
Organism's stimulus response
Kinesis is movement or activity, especially in response to a stimulus.
In biology, it describes an organism's undirected movement triggered by environmental factors like light or temperature—distinguished from taxis, which is directed movement.
The suffix -kinesis appears in compounds: telekinesis (moving objects with the mind), psychokinesis, cytokinesis (cell division).
The related prefix kine- appears in kinetic and cinema.
