- Using it to describe general heat preference rather than directed growth.
- Misspelling as 'thermotropizm'.
FAQ
Frequently Asked Questions
No. 'Liking' is anthropomorphic. Thermotropism is a specific, directional growth response to a temperature stimulus, which can be positive (towards warmth) or negative (away from it).
Typically, the term is used for plants, fungi, and some stationary organisms or their parts. The directed movement of a whole animal in response to heat is usually called thermotaxis.
There is no direct single-word antonym. 'Athermotropic' describes a lack of response. The opposite response would be 'negative thermotropism' (growth away from the stimulus).
It's a highly specific term from a scientific sub-field (plant physiology). Most people encounter the more general concept of plants responding to their environment without needing this precise term.
The directional growth or movement of an organism, or part of an organism, in response to a temperature stimulus.
Thermotropism is usually technical/scientific in register.
