What is the Difference Between Kinesis and Taxis?

🆚 Go to Comparative Table 🆚

Kinesis and taxis are two types of movements shown by organisms in response to different stimuli. The main differences between kinesis and taxis are:

  1. Direction of movement: Taxis refers to the directed movement of an organism in response to a stimulus, while kinesis refers to the undirected movement of an organism in response to a stimulus.
  2. Examples: Examples of taxis include phototaxis (response to light), chemotaxis (response to chemicals), and geotaxis (response to gravity). Examples of kinesis include orthokinesis (related to speed) and klinokinesis (related to turning).

In summary, taxis is a directed movement of an organism or cell towards or away from a stimulus, while kinesis is an undirected, random movement of an organism or cell in response to a stimulus.

    • Comparative Table: Kinesis vs Taxis

    Here is a table comparing the differences between kinesis and taxis:

    Feature Kinesis Taxis
    Definition Non-directional movement of a cell or an organism towards or away from a stimulus
    (e.g., light, water, temperature, gravity, chemicals)    		 Directional movement of an organism or cell towards or away from a stimulus
    Examples - Orthokinesis: Movement speed varies with the stimulus intensity
    - Klinokinesis: Movement direction and speed vary with the stimulus intensity    		 - Phototaxis: In response to light
    - Chemotaxis: In response to chemicals
    - Thigmotaxis: In response to touch
    Type of Movement Random and non-directed Specific directional response
    Purpose Avoiding unfavorable conditions or locating resources Finding food, mates, or suitable environments
    Speed Movement speed is dependent on the intensity of the stimulus Movement is not rapid and is always directed towards or away from the stimulus

    In summary, kinesis is a non-directional movement in response to a stimulus, while taxis is a directional movement. Kinesis is a more generalized response, allowing organisms to avoid unfavorable conditions or locate resources, whereas taxis is a more precise and directed response, enabling organisms to find food, mates, or suitable environments.
