Speaking about an experiment done with plants and the response of a plant that didn’t make it to a pole before another one:

What is interesting is the behaviour of the loser: it immediately sensed the other plant had reached the pole and started to find an alternative. This was astonishing and it demonstrates the plants were aware of their physical environment and the behaviour of the other plant. In animals we call this consciousness.
