Do plants think?

Sadly, you won’t find ponderous plants like Treebeard the Ent from "Lord of the Rings" in the forest.

Plants don’t have a central nervous system, so thought (as we normally define it) isn’t possible. But plants can sense their environment, respond to insect attacks and are even capable of limited movement. These reactions are driven by chemical signals – rather than nerve impulses – so it’s more like your immune system or unconscious hormonal responses, than conscious or deliberate thought.
