Detailed explanation-1: -Plants may seem static, rooted to the ground and unaware of what’s happening around them. However, this couldn’t be further from the truth. Plants sense the world including sensing light, touch, chemicals, microbes, animals and temperature, in unique ways that are often invisible to us.

Detailed explanation-2: -All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental cues.

Detailed explanation-3: -Plants respond to their environment in a variety of ways. The response of an organism, usually a plant, to an environmental stimulus is called a tropism. Some common plant stimuli include light, gravity, water, movement of the sun, and touch. The naming of the tropism is associated with the stimulus.
