100 Great Secrets from the Life of Plants

Scientists believe that plants possess feelings, intelligence, have memory, a sense of time, can distinguish colors, and communicate with each other or warn one another. They can recognize threats, tremble with fear, may call for help; they are capable of... interacting with each other and other living beings from a distance; they differentiate the mood and intentions of people; the radiation emitted by them can be recorded by sensors. They cannot run away in case of danger. They have to be more attentive and watch what is happening around them. As it turns out, plants react to people, noise, and other phenomena, but how they do this remains a mystery. No one has yet managed to get closer to solving it.
This and much more is covered in the latest book of the series.
