Answer:
Scientists have shown that plants can detect various wavelengths and use colors to tell them what the environment is like. When a plant grows in the shadow of another, it will send a shoot straight up towards the light source. It has also been shown that plants know when it is day and when it is night.

Plants also respond to ultraviolet light by producing a substance that is essentially sunscreen so that they do not get sunburned. Plants can sense weather changes and temperatures as well.
