<u>A tissue is simply a group of specific kind of cell that have a specific role.</u>
- For example: The nervous system contains cells called neurons that have ability to transmit message from one place to another and allow us to respond to any environmental stimuli, such as heat, cold, danger etc.

Thus we see that different types of cells have special functions and all these different cells coordinate with each other to make an organized and functioning body of a living organism.
