“PLANT BIO-ATTENTION is what we may call “hyper-attention,” as every vertical shoot, leaf and rootlet monitors the minutest environmental variations proximate to it. Far from a redundancy, the plant’s non-totalized intelligence is explicable, in cognitive terms, as a paralleling processing model, with every organ of intentionality playing the role of a parallel processor.”
