This controversial article proposes that plants exhibit intelligence, challenging the notion that intelligence is exclusive to mobile organisms. It argues that plant behavior reflects complex environmental computation, necessitating a re-evaluation of plant cognition and responses.

Area of Science:

  • Plant behavior and cognition
  • Comparative intelligence studies

Background:

  • The term 'intelligence' is rarely applied to plants, often overlooking their complex environmental interactions.
  • This omission stems from a bias towards mobile organisms, neglecting the capabilities of sessile life forms.

Purpose of the Study:

  • To controversially propose the application of the term 'intelligence' to plant behavior.
  • To explore the implications of plant intelligence for understanding plant signal transduction and environmental perception.
  • To investigate the potential for learning and memory in plants.

Main Methods:

  • Conceptual analysis and literature review.
  • Discussion of plant signal transduction pathways.
  • Exploration of plant sensory discrimination and environmental image construction.

Main Results:

  • Suggests that plant behavior demonstrates complex environmental computation.
  • Highlights the sensitivity and discrimination with which plants perceive their surroundings.
  • Poses critical questions about whole-plant response computation.

Conclusions:

  • Applying the term 'intelligence' to plants can enhance our understanding of their complex capabilities.
  • Further research into plant learning and memory is warranted.
  • Plant behavior warrants a re-evaluation through the lens of cognitive science.
