I found useful information about plant sense from your blog as, How do plants sense a change in the environment? You have explained, "Plants can sense weather changes and temperatures" ( here ). Please explain how to identify the plant's sensing process and which kind of method and techniques are used to identify them?

I don't know the exact mechanism; however, because plants possess no sensory organs, it would have to be some kind of chemical change. I also suspect that the answer depends on the plant in question, since plants have such different responses to temperature, and have evolved them convergently.

Answer 2:

Here's a cool example:
In their experiments, Appel and Cocroft found that recordings of the munching noises produced by caterpillars caused plants to flood their leaves with chemical defenses designed to ward off attackers. "We showed that plants responded to an ecologically-relevant 'sound' with an ecologically-relevant response," says Cocroft. Source.
