Definition
Meaning and Definition
The movement of an organism or cell toward or away from a source of heat.
A directed movement or orientation of a living entity in response to a temperature gradient. This can also refer to artificially guided motion in certain materials or systems in response to temperature changes.

Common Mistakes When Using “thermotaxis”
- Misspelling as 'thermotaxsis' or 'thermotaxys'.
- Confusing with 'thermotropism' (growth response) or 'thermoregulation' (maintaining internal temperature).
- Using it as a verb (e.g., 'The cells thermotaxised'). The verb form is not standard; use 'exhibited thermotaxis' or 'underwent thermotaxis'.
FAQ
Frequently Asked Questions
No, it is a highly specialised scientific term rarely encountered outside of technical literature in biology, microbiology, or biophysics.
Primarily used for living organisms (cells, bacteria, animals). However, by analogy, it can sometimes be applied in materials science to describe directed movement of particles or synthetic systems in response to temperature.
Thermotaxis is a directed *movement* toward/away from a heat source. Thermoregulation is the broader process by which an organism *maintains* its internal body temperature within a certain range, which may or may not involve movement.
Use it as a noun, typically as the object of a verb like 'exhibit', 'show', 'demonstrate', or 'study'. Example: 'The research paper investigates the molecular basis for thermotaxis in fruit fly larvae.'
The movement of an organism or cell toward or away from a source of heat.
Thermotaxis is usually technical/scientific in register.
Thermotaxis: in British English it is pronounced /ˌθɜːməʊˈtæksɪs/, and in American English it is pronounced /ˌθɜːrmoʊˈtæksɪs/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'THERMOmeter' measures heat, 'TAXI' moves you somewhere. THERMOTAXIS is how an organism 'takes a taxi' towards or away from heat.
Conceptual Metaphor
TEMPERATURE IS A GUIDE/ATTRACTOR. Organisms are portrayed as being passively pulled or actively navigating along a 'path' laid out by temperature differences.
