Most people don’t think twice about plucking a pretty flower or breaking off a tree branch. That is because we know that plants don’t have a brain or a nervous system like humans do. However, plants can react to outside elements and protect themselves to survive.
Humans have five senses – taste, touch, smell, hear and sight that they use to interact with the world around them. If we taste something sour, you can tell from our facial reactions, or if the temperature in a room is cold, we will cover ourselves with a jacket.
