Human: What are some of the major differences between a fender and a hood? Assistant: 
Some of the major differences between a fender and a hood include their purpose, design, size, shape, material, and function. A fender is designed to protect the vehicle from damage caused by debris or other objects hitting the body of the car. It typically covers the front and rear wheels, as well as the lower part of the car's body. A hood, on the other hand, is designed to provide an air intake for the engine and is usually located at the top of the car’s engine compartment. Additionally, a fender is made out of a hard plastic material while a hood is made of metal.
