I have actually given some thought to this subject. I'm puzzled why anything would evolve to that situation.

Probably because when the first land plants evolved, there was nothing to run from - no animals around to eat them yet.

Besides, they're not totally defenseless - consider how many toxic varieties of plant there are. That caffeine in your coffee might make you a bit jittery, but that's because you have a slick and sophisticated liver. Most other animals would just be stone dead ;)

Yes, I've read a number of artricles on plant defenses. Here's one about a symbotic relationship plant/fish. On the Amazon River there is a tree that dispences it's seeds into the water and the seeds are eaten by a particular fish. The fish eats very little else. The seeds of this tree will not germinate until it has passed through the gut of this fish. They are dependant on each other for survival.
