Plant perception (physiology)
This article is about the physiology of perception and response in multicellular plants. For "plant emotion" especially as applies to the work of Cleve Backster, see Plant perception (paranormal).
In botany, plant perception is the ability of plants to sense the environment and adjust their morphology, physiology and phenotype accordingly. Research draws on the fields of plant physiology, ecology and molecular biology. Examples of stimuli which plants perceive and can react to include chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, physical disruption, and touch. Plants have a variety of means to detect such stimuli and a variety of reaction responses or behaviors.
A number of studies have shown that plants feel pain, and vegetables are picked and often eaten while still alive. Animal rights activists are often in the news, but has anyone ever protested for vegetable rights?
