Researchers: Yes, plants have nervous systems too:

Plants turn out not only to have nervous systems but nervous systems that are analogous to those of animals. Recently, a research team observed the outcome of wounding a plant called Arabidopsis thaliana, a mustard often used in experiments. The really remarkable part of this apparent convergent evolution of animals and plants is that “these channels are activated by extracellular glutamate, a well-known mammalian neurotransmitter”

Of course, insects find a way around the communications among plant nervous systems. One insect, for example, gets plants to transmit false information to other plants. … Mind Matters at

Evolution appears to converge on goals—but in Darwinian terms, is that possible? Using glutamate as a neurotransmitter is an example of convergence between mammals and plants.
