The changes in the environment to which the organisms respond and
react are called stimuli such as light, heat, cold, sound, smell, touch etc.
Both plants and animals respond to stimuli but in a different manner.

neurons, and is specialized for conducting information via electrical
impulses from one part of the body to another.
Receptors : Are specialized tips of some nerve cells that detect the information
from the environment. These receptors are located in our sense organs.
