Plants may sense, remember, and adapt like true decision-makers

Plant Signaling
The seedling bending toward light on your windowsill or the root correcting its path around a buried rock in your garden bed is running a sensing-and-memory system this paper argues deserves to be called intelligent behavior, not just reflex.
This paper makes the case that plants are intelligent in the same basic sense animals are: they adjust their behavior based on experience to survive. The author walks through how plant cells pick up signals like calcium and relay them through tiny fatty structures in their membranes, how roots and shoots use backup sensing systems to find which way is up, and how plants hold onto at least five different kinds of memory throughout their lives.
Key Findings
Plant intelligence is redefined using the same adaptive-behavior standard applied to animal and artificial intelligence, countering claims that the concept is controversial.
Early calcium-based cell signaling is proposed to run through complex protein structures anchored in mobile lipid rafts, acting as a cognitive-like process.
Gravitropism (how plants sense and respond to gravity) relies on two separate sensory mechanisms, illustrating fail-safe backup systems plants use to survive unpredictable wild environments; the paper also outlines five distinct categories of plant memory.
chevron_right Technical Summary
A plant scientist argues that plants show real intelligence, defined as the ability to adapt behavior to changing conditions, not human-style thinking but a measurable form of responsiveness. The paper reviews how plants sense gravity, use calcium signals and cell membranes to process information, and store at least five distinct kinds of memory.

Aspects of plant intelligence (ii).
Plant intelligence was earlier described as adaptively variable behavior during the lifetime of the individual plant (Trewavas 2003). This general definition for animals and plants (biological inte...

Plant intelligence is a field of plant biology that investigates how plants perceive, integrate, and respond to environmental information in intentional and flexible ways that serve their survival and growth. Understanding these processes challenges traditional views of cognition as
