Movement or motion that occurs in response to external stimuli or in a way different from the normal or expected pattern.
From Greek 'allo-' (other) + 'kinesis' (motion, movement); a biological term describing altered or irregular movement patterns in organisms.
When plants grow toward light or roots grow downward against gravity, they're not just passively responding—they're performing allokinesis, showing that even organisms without brains can detect and respond to their environment!
