Plants can see, hear and smell – and respond

Depends on your definition of aware. I'd certainly say plants can be physiologically aware of something without having the capacity to be consciously aware.

Yup, and not only murder, is torture in fact. You unroot an innocent young lattice, begin tearing off some leaves and chop, chop, chop the plant finely, then squeeze vinegar and salt in the open wounds, smash it with the teeth and finally disolve with acid the remains. Is horrifying if we think about it.

You don't make friends with salad.
