用法筆記

Non-specialist speakers more often use phrasings like 'growth in response to light.'

常見錯誤

❌The plant showed tropistic to the light.
✅The plant showed a tropistic response to the light.
💡tropistic is an adjective, not a noun; it must modify a noun.
❌The tropistic is caused by sunlight.
✅The tropistic response is caused by sunlight.
💡again, tropistic needs a following noun; use 'tropism' as the noun form instead.
