What term refers to a non-directional response involving the random turning and movement of an organism?

The term "klinokinesis" refers to a non-directional response exhibited by organisms, characterized by random turning and movement. In a klinokinetic response, the frequency of turns increases in response to a stimulus; however, the organism does not move towards or away from that stimulus in a directed manner. This behavior can be observed in various organisms as they navigate their environment, allowing them to effectively explore areas and encounter resources or avoid hazards.

In contrast, orthokinesis involves a change in the speed of movement in response to an environmental stimulus but does not include directional turning, while tropism refers to directional growth responses in plants, often towards or away from stimuli like light or gravity. Thigmotropism is a specific type of tropism related solely to touch or physical contact. Understanding these distinctions is crucial in studying how organisms adapt and respond to their surroundings.
