Orchids might be the sexiest flower in the greenhouse. Its very name comes from the Greek word for "testicle!" And its reproduction methods are pretty exotic too.
Thinking allows us to solve problems, plan ahead and defend ourselves from outside threats. It's what separates us from "lower" life-forms like plants, right? Well, maybe not.
Though they may be stuck in one place, plants have proven to possess a surprising array of capabilities. But the ability to feel pain? Scientists are learning that the possibility isn't as crazy as it sounds.
