What a Plant Knows, the biologist Daniel Chamovitz describes sophisticated information‑processing capacities that plants use to control their movements in response to stimulation. Plants not only “follow the sun” by bending their stems, they also align their leaves in such a way as to (a)
maximize exposure to light and thereby promote growth. Some plants actually anticipate sunrise from “memory,” and even when deprived of solar signals retain this information for several days. In
Brilliant Green, Stefano Mancuso and lessandra Viola argue that plants possess not only the senses of sight, touch, smell, and hearing, but more than a dozen other (b)
sensory capacities that humans lack. For example, the roots of plants sense the mineral and water content of the soil and alter their direction of growth accordingly. Some are (c)
reluctant to label plant movements as behaviors, since they lack nerves and muscles. But just as they are able to breathe without lungs and digest nutrients without a stomach, plants have the ability to move (behave). We should not dismiss the (d)
absence of behavioral capacities in an organism simply because it lacks the physiological mechanism that is responsible for the behavior in animals. Plants clearly sense the environment, learn, store information, and use that information to guide movements; they behave. One might say that there is certain “intelligence” to their behavior. This is true as long as intelligence is defined in terms of the ability to solve problems through behavioral (e)
interactions with the environment, rather than with respect to mental capacity.
