Do plants sleep?
Plants don’t have central nervous systems that seem to be key in what we think of as sleep in humans. But plants do have circadian rhythms tuned to Earth’s 24-hour light-dark cycle, which they maintain even if they’re kept in light fulltime, just as we do.

Do trees talk to humans?
