Agreed, and I spent like a decade in protein engineering and pre-biotic chemistry.

And if someone really wants to be a pedant about it, go ahead and prove conscious "intent" is inherently different than, not just a more complex form of, what's going on here. If someone's managed to solve all of the philosophy around consciousness, self, and intent, they could really save us all a bunch a time! Until then, pedantically, you're not wrong to say the plant "knows" to do this as much as I "know" to pay my rent; it's all just chemical reactions based on environment.
