For the record, I agree with you.

BUT, as a biologist, I often find it amusing that people discount plants completely. It's easy to forget that they are alive too. Fundamentally, they aren't so different from you or a turtle or a fruit fly. Different cellular structure, sure. Not easily recognizable "consciousness", absolutely. Non-motile, check.

However, plants are very much alive. They react to stimuli, survive in hostile environments, procreate. They are more alien to our sensibilities, but they are arguably not very much different in the grand scale of things.
