Taxes: – is a movement of an entire cell or organism (i.e. locomotion) in response to and directed by an external stimulus. Tactic responses can be described as positive or negative and can be further classified according to the nature of the stimulus
Types of tactic responses
There are many types of tactic movements including
- Phototaxis (stimulation by light)
- aerotaxis (stimulation by oxygen)
- anemotaxis (by wind)
- barotaxis (by pressure)
- chemotaxis (by chemicals)
- durotaxis (by stiffness)
- electrotaxis or galvanotaxis (by electric current)
- gravitaxis (by gravity)
- hydrotaxis (by moisture)
