What do plants, robots, and pizza have in common?

Answer: This TED talk!
The speaker, Stefano Mancuso talks of plant intelligence. He shows some cool slow motion footage of plants “playing”, “sleeping”, etc. One of the things that sounded interesting was his assertion that plant root tips are individual brains. This forms a “networked” brain similar to how computers relate to the internet. It’s a vast network. Kinda makes me think of Avatar.
