To smell the food we eat. To smell flowers. Taste Tasting food. Without taste we wouldn't know if food was good or not. Taste lets you know that candy is sweet and lemons are sour.
Touch Can tell if a surface is hot or cold.
To feel the soft fur of your cat. Hearing Listening to music. Listening to friends. Our eyes have special cells which pick up images. There are special cells that line our nose that allow us to smell things.
