Without plants, there would be no food, no animals of any sort, no life on earth at all. Yet for most of the time their lives remain a secret to us, hidden, private events.The reason is merely a difference of time. Plants live on a different time-scale from ours. Though not obviously to the naked eye, they are constantly on the move: developing, fighting, avoiding or exploiting predators or neighbours, struggling to find food, to increase their territories, to reproduce themselves, to find and hold a place in the sun. We only need to learn to look.
